Re: Required help for reducing High Bandwidth Utilization of Guacamole
Dear,
Thanks your valuable replay .
I observe that when data send from server to client in image/PNG and PNG
take to much bandwidth rather than *Webp.*
*Please guide us how i am enable or decode image data/PNG to image
data/Webp in guacamole server with tomcat with compression?*

Manoj,
If you've isolated your bandwidth issue to Xrdp that's useful. My
comments around FreeRDP could be equally applied to Xrdp insofar as
there may be some tweaks available, or some useful resource your company
could provide the Xrdp project.
I've not had a lot to do with Xrdp myself so there's nothing more I can
say. Others may be able to comment but ultimately you will probably need
to research that yourself. Should you achieve your goal it would be
useful to post back what you did to the group.
I see Mike has replied to you regarding the browser <-> Guacamole
disconnect you're experiencing.

The timeout at all levels of the Guacamole stack is 15 seconds, well above
400-500ms. If you are seeing disconnects, the cause is not the latency of
your link, nor is there likely some parameter you need to change within
Guacamole. It is more likely that something on the network is interfering
with the Guacamole connection, such as a proxy which does not support
WebSocket (or is not configured properly for WebSocket) and which buffers
HTTP connections.

ivanmarcus,
Thanks for cooperation .
Xrdp observation----------
As per observation and experience i think the measure issue at Xrdp side .
Xrdp send the images in bitmap and jpeg compression but i could not see the
compression is done or not.
second thing is when you move the mouse pointer on RDp session then it also
send the bytes .
third one is , its calculate the RDP desktop in BPP,Width and Hight and
show this bitmap to client . (rendering)
TLS 1.2 calls is default implemented in and it send request(read write) in
100 ms .
At Guacamole Side---
When Browser to Guacamole in idle no send receive .
But when connect to RDP session its continuously checking keepalive then
some bytes to be increased .
When at client side latency is 400-500 guacamole disconnected frequently .
can you help in this to increased the parameter for checking the
connection to keepalive and checking latency.

Thank you for doing this test. From the above comment I take it that
what you experience with the FreeRDP client <-> Xrdp is similar to what
you have with Guacamole <-> Xrdp, and results in the issue you raise.
As you're probably aware Guacamole uses FreeRDP for RDP connections to
Xrdp. If the bandwidth requirement using FreeRDP directly, without
Guacamole, is problematic for you then it's likely the issue results
from FreeRDP rather than Guacamole.
FreeRDP is a separate project to Guacamole. You should research your
issue in relation to FreeRDP, rather than Guacamole, as this may give
you the answers you're looking for. Possibly it's just a function of the
way FreeRDP works and you will simply need to allocate more bandwidth as
Mike has already suggested, or there may be some parameters you can tweak.
Concluding, I note that FreeRDP, as with Guacamole, is an open-source
project. If you've discovered an issue that is causing you a problem
then your company could consider putting some resource into
fixing/improving that issue? Not only would that make things better for
you, it would also assist the wider community who've provided the base
for your service, including, ultimately, Guacamole.

Dear,
When i am connecting through MSRD client to xrdp --
In idle mode Bandwidth utilization is low ,but when i move mouse pointer
over windows and run my application bandwidth is utilized high.
In reverse i am connect MSRD client to MSRD (windows) host in idle
condition bandwidth is low , when i am move mouse pointer over windows or
run application on windows host the utilization of bandwidth is very low.
When connect to FreeRDP client-> xrdp ,bandwidth utilization is also High
in idle condition. In running condition using freerdp client utilization
is High.

Manoj,
I think the answer you're giving is 'yes' - ie. that the issue you're
experiencing is in fact between Guacamole and the Xrdp machine(?).
In that case, for the next step, could you try connecting to your Xrdp
machine directly via:
(1) MSRD client
(2) FreeRDP client
And compare the experience/bandwidth utilisation of these two clients
(doing the same tasks, incl idle)?

Re: Required help for reducing High Bandwidth Utilization of Guacamole
Posted by Manoj Patil <ma...@gmail.com>.
dear Mkie/
ivanmarcus
can i share a html code of MSRDC . through this html you can able to
connect windows machine.
share this html on that mailid or any personal maild ?
see the snap shot .
When i am check MSRDC at high network latency(600-700 ms) it run smoothly .
but in guacamole breaks the connection in time to time(connect-reconnect).
Also we check at this latency typing is very fast there is no laggy in
keyboard typing.
In guacamole to Xrdp at same latency there is keyboard laagy occur means
slow typing at client end.
we also see when i am connect to MSRDC(windows) host through client its
take first time 8-10 kbps continilously transfer data in transection mode .
in idle mode there is no any bandwidth utilization.

Manoj,
Perhaps I'm struggling to understand completely, but maybe we should
just go through this one step at a time.
(1) Is the bandwidth issue you're presenty raising between Guacamole and
the local (Xrdp) client - NOT between Guacamole and the remote browser?

Re: Required help for reducing High Bandwidth Utilization of Guacamole

Dear ivanmarcus,
To be specific. You say MSRDWC uses a lot less bandwidth than Guacamole,
however (if I understand correctly) from what you say you're using
Guacamole with a Xrdp client machine, and MSRDWC with a MSRD client
machine. I suggest you should first test with Guacamole to the MSRD client,
and then MSRDWC to the *same* client with the *same* parameters and the
*same* series of tests. IOW the *only* change in the lineup is MSRDWC vs
Guacamole - NOT the client machine as
I am done the setup of MSRDC at my place and measuring the sam scenario
Guacamole to xrdp client ----
When connecting through browser to guacamole it's low bandwidth . when
connect guacad to xrdp host its huge bandwidth.
Guacamole to MSRDC client--
We test this setup with guacamole to MSRDC host through client there is
also a bandwidth utilization . we measure theough wireshark
MSRDC to same client --
When i am connected to MSRDC with same parameter of bpp, width , height
etc and measure through wireshark there is tremendous different , its take
very low bandwidth .
When I am in idle mode in guacamole to xrdp its continuously check
keepalive and bandwidth utilizated that time.
When i am in idle in MSRDC there is no keepalive checking see in wireshark
hence bandits is very low .

Manoj,
We may have exhausted our ability to help. As Stefan has pointed out
there have been a number of suggestions and explanations around the
issue you raise; it could be useful if you were to pursue those in the
first instance.
One thing that strikes me from your latest post is that you're
introducing too many variables when attempting to compare systems. If
you want to make comparisons then you should start with as identical a
system as possible and change just *one* parameter first. In this way
you will generally be a lot clearer around what changes have an affect
on something.
To be specific. You say MSRDWC uses a lot less bandwidth than Guacamole,
however (if I understand correctly) from what you say you're using
Guacamole with a Xrdp client machine, and MSRDWC with a MSRD client
machine. I suggest you should first test with Guacamole to the MSRD
client, and then MSRDWC to the *same* client with the *same* parameters
and the *same* series of tests. IOW the *only* change in the lineup is
MSRDWC vs Guacamole - NOT the client machine as well.
Moving on from this, I don't have access to MSRDWC and have never used
it but if possible the next test might be to utilise it with an Xrdp
client machine and compare that with Guacamole to the *same* client.
Such logical steps would lend much more credence to your results, and
may provide a clearer pointer to you as to where the issue, if there is
one, lays.

Re: Required help for reducing High Bandwidth Utilization of Guacamole
Posted by Manoj Patil <ma...@gmail.com>.
Dear
I know the discussion is going on .., but still we try to minimised the
bandwidth utilization. I see in xrdp code there is a bitmap and jpeg cache
and compression with respectively bpp(bit per pixel), width and height .
but guacamole can done the compression and cache the bitmap and jpeg.
We see in guacamole they used ping and webp so I think the cache and
compression is mismatch.
Please if it correct?

Hi Manoj
Several Guacamole users have made useful suggestions over the course of the discussion.
Ultimately, the resolution of your issues is in your own hands.

Dear ivanmarcus/mike,
The MSRDP setup is done at my end for testing purpose with same user ,same
screen,same depth etc. we measure the bandith for singile session and it is
too low. i am already sharing a snapshot in preious mail.
*My point is if i used MSRDP web client to acees the server it take low
bandwidth utilization . when i am using guacd with xrdp it uses high
bandwidth.*

Re: Required help for reducing High Bandwidth Utilization of
Guacamole
Posted by ivanmarcus <iv...@yahoo.com.INVALID>.
Manoj,
I've followed this thread with some interest, and have learnt something
from what Mike's been saying about how Guacamole handles image
compression etc.
I'm not able to contribute much from a softwarec perspective but there
are a couple of things that I wonder about.
In your tests it appears to me that, generally, the Guacamole <-> xrdp
traffic is much higher than Tomcat <-> browser, as one would anticipate.
Assuming your Guacamole <-> xrdp connections to be on an internal 1GbE
network then one would expect Tomcat <-> [external] browser experience
to be much quicker than say xrdp <-> [external] MSRD client.
In an earlier post you said:

From this I was interested to see what information there was regarding
the bandwidth requirements for MS RD Web Client vs MS Terminal Services
Client.
I found this website article:
https://www.rdsgurus.com/microsoft-rd-web-client-html5-performance-testing-part-1/
Although not completely clear my take on their results is that MSRDWC
could use similar, or possibly more, bandwith than MSTSC (or it could
use ~1/2 in some cases). They explicitly state further research is
needed so the results should be considered provisional at this time.
*If* these results are in the typical ballpark then it would seem to me
somewhat at odds with what you said earlier, and with the results you've
charted.
To clarifiy.
(1) From the article let's say MSRDWC bandwith typically = MSTSC bandwith.
(2)You measure Guacamole <-> xrdp bandwidth significantly higher than
Tomcat <-> browser (let's say this equates to what we'd expect typical
MSTSC bandwidth to be).
(3) Extapolating; your colleague company is using MSRDWC, therefore with
no other changes or tuning we might ordinarily expect their bandwith
requirements to be higher than yours since, from your's and Mike's data,
the Tomcat <-> browser bandwidth should effectively be less than MSRDWC.
(4) Yet you've said they have twice the connection numbers with 1/5
available bandwith, and although not stated the intimation is that their
user's experience could be better than yours?
Now I realise I'm drawing a fairly long bow, and making some pretty wild
assumptions based on possibly erroneous data, but at this point the
comparision just doesn't add up.
There are many possibly variables that might explain this but I wonder,
initially, if there are some other differences in what service your
colleague company is delivering compared with yours? For example is
theirs a much reduced colour depth, is it limited to a specific app with
little screen updates, do they have burst mode data capacity, do they
have fewer _concurrent_ users etc?
Ultimately Mike has said several times that you simply need to allocate
more resource for what you're doing, but it may assist yourself and the
community if you could obtain a similar bandwith log from your colleague
company as you have for yours. It would be good if the data were
standardised as much as possible (ie. perform exactly the same desktop
tasks) and the same colour depth settings etc were utilised.
If this were effected I think we'd have a much better idea as to the
bandwith requirements of Guacamole vs MSRDWC. From this one might then
know if there's any real (comparative) issue between your service and
that of your colleague company, or not. It could also give some
potentially useful info around Guacamole/MSRDWC performance...

Dear Mike,
i am sure that measuring the same sessions, connecting to the same RDP
server, and that you are using the same display size, performing the same
actions, seeing the same graphics.
I am go through as per your suggestion and calculate the bandwidth for
below action.
browser <--> Guacamole traffic and the guacd <--> RDP traffic.
As per observation browser <--> Guacamole traffic is very low around 27K .
guacd <--> RDP traffic is very high in working condition is around
2876K.
From the below observation guacd <--> RDP traffic and
bandwidth utilization is very high.
plz find attached snapshot of measuring bandwidth.

There isn't really anything to resolve.
As already noted in this thread, the bandwidth you've measured for
Guacamole looks fine and the bandwidth we've measured for Guacamole looks
fine. It's interesting that you're seeing lower RDP utilization in one of
your tests, and worth looking into seeing why that might be the case, but
other than an interesting research problem that might eventually yield
further performance improvements to Guacamole, there's nothing to resolve.
Assuming that what you're comparing is an indeed apples-to-apples
comparison, then there is probably something to be discovered which would
further improve things, but I'm not going to be able to tell you what that
is because I don't know it yet. All I can tell you right now is that if
you're finding you haven't allocated sufficient resources, then you need to
allocate sufficient resources.
As per your snanshot RDP take to much bandwidth utilization .

If you want to compare bandwidth usage reliably, you will need to measure
and compare the two sides of the same session: one measurement being the
browser <--> Guacamole traffic and the other being the guacd <--> RDP
traffic. For example, here's my statistics for the first week of December
last year:
[image: glen-demo-stats-2019-12-01-through-2019-12-07.png]
The graph shows total Guacamole bandwidth usage (green line) against RDP
usage (orange line) for the same servers across all sessions. The purple
line is the total number of active sessions. In general, the two bandwidth
lines follow each other, however I've always observed the RDP line to be
significantly higher, presumably due to using poorer image compression. The
only times I've seen the Guacamole line peek (slightly) above the RDP line
are when there is extremely low activity.
If you are absolutely sure that you are measuring effectively the same
sessions, connecting to the same RDP server, and that you are using the
same display size, performing the same actions, seeing the same graphics,
etc. between them, I'm not sure what would account for your measurements
showing the opposite behavior.

Dear,
I am deployed the Microsoft environment at my end and measure the bandwidth
data send and received.
using wireshark.
please find the attached file one is microsoft web rdp bandwidth
calculation using wireshark and second snapshot is guacamol server

No. PNG is compression, and an average of ~86 Kbps is not high network
load. There is some overhead from base64, but that overhead is all but
nullified by (1) the gzip compression that is generally automatically
applied to WebSocket and (2) the speed that browsers can process that
base64 data compared with alternative mechanisms that lack the overhead.

From measurements of real-world use of the live demo environment deployed
by my day job, I see the opposite of this. The overall bandwidth used
between the users' browsers and the Guacamole servers is significantly less
than the bandwidth used by RDP between guacd and the Windows servers.

Re: Required help for reducing High Bandwidth Utilization of Guacamole

Dear,
Thank For your appreciation .
The only thing that I noticed is that there is no compression between the
server and the client.
Meaning that full sized base64 encoded PNG images are send to the client,
which causes a high network load.
i am try to find out why more bandwidth is required for 600 connection and
how to reduced it.
My Observation is---
we observe that in my colleague company those people used Microsoft remote
desktop Web client (using activex) for 1200 connection in 10 Mbps for huge
transaction. and
we used Xrdp+wine+Guacamole with 600 connection with 50 Mbps bandwidth .
what protocol they are used ( Microsoft remote desktop Web client ) is
taking less bandwidth compare with Guacamole.
if we tune guacamole like that Microsoft remote desktop Web client it is
valuable for all in low bandwidth.
without your help we can not do any changes in guacamole server.
Please guide.

No, whether WebP performs better than PNG depends on the content of the
image, and there is more to performance than simply bandwidth. Guacamole
attempts to detect this automatically and use whichever will produce the
best user experience. Forcing WebP across the board will likely perform
noticably poorly.

Guacamole already does this automatically, and it has nothing to do with
Tomcat.
Really, I think you are chasing red herrings, trying to solve a problem
that isn't actually in the software. Your recording and bandwidth
measurements both show things working nominally and that the bandwidth
usage is not high.
I believe the ultimate issue is that you're trying to cram 600 connections
down the same 50 Mbps pipe, and that you are not going to achieve
reasonable performance for those 600 connections simply because that is not
a reasonable resource allocation. Guacamole will still work, but it will be
strongly limited by what you've given it to work with.
It doesn't hurt to experiment (it's the only way progress happens) and
you're more than welcome to dig through the source on your own and see
whether tweaking things with respect to WebP vs. PNG vs. JPEG helps. If you
do discover an improvement, it would be a very welcome contribution.
That said, keep in mind:
* This and many other things have been tried before. Guacamole is as it
currently is because of this extensive testing and design. Using WebP
across the board has been tested, and it performed badly.
* There are bandwidth, encode time, and decode time tradeoffs in using
these various compression schemes. The idea of using WebP across the board
(for browsers that support it) was rejected during initial testing for this
reason - PNG often compresses faster and nearly as well, with the slower
encode time of lossless WebP outweighing any benefit and ultimately making
things slower.
* While there are likely cleverer ways to determine whether PNG, WebP, or
JPEG should be used, and cleverer algorithms to be applied to Guacamole's
cost optimizer, it's unlikely to be as simple as "just use WebP" and
unlikely to produce the order-of-magnitude improvement you would need to
fit all those connections in 50 Mbps.
