Guacamole Performance
Hi,
I've recently installed a guacamole based tool to access remote machines. In comparison to using TurboVNC directly to the same machine, guacamole seems to perform very poorly (low fps, regular stutters, noticeable delay between input and feedback) and on safari some of the colours seem to be messed up. I'm just wondering is this possibly because I've set it up differently in some way to what it should be or if this is just the nature of the additional web layer on top of vnc?
Another small issue I've found is that the text becomes blurry if the browser stretches the resolution of the session. I try to set the size to be 100% (in the ctrl+alt+shit menu) but the minus button doesn't let me go below 118% unless I resize my browser window)

seems to perform very poorly (low fps, regular stutters, noticeable delay

Hi Alex,
No, poor performance is definitely not expected, nor should there be any
browser-specific difference in color.
What tool are you referring to?
What version of Guacamole is involved, and how is it deployed? Any proxies?
SSL?
Thanks,
- Mike
RE: Guacamole Performance

Hi Mike,
The tool I was talking about is just a web application that launches the vnc sessions on the requested resource and passes the authentication details to guacamole.
To eliminate some possibilities, I’ve just installed guacamole (without the tool and built from the source on apache github) on a fresh Debian Jessie VM and the performance is still subpar to turbovnc viewer.
The VM itself has 2 cores with 4 GB of ram with a 1gbit network to my laptop. I’ve been watching the cpu and mem usage and it doesn’t seem to be bottlenecking the performance.
I’m connecting to a turbovnc server on the same VM but I’ve tried different remote machines also.
Guacamole is running inside tomcat and I’m using apache for the websocket proxy.
Also, I mentioned in my original email that I wasn’t able to set the size of the session to 100% without resizing the web browser window itself. Am I missing something obvious? The image looks a lot sharper and much easier to look at when it is not being stretched.
Is there anything else you recommend for me to try?
Thanks,
Alex

Hi Shanon,
I’m not sure about the version numbers but I cloned guacamole-client and guacamole-server directly from https://github.com/glyptodon about a month ago so it should be pretty recent.
The latest development will be on the Apache repositories, so definitely try against those:
https://github.com/apache/incubator-guacamole-client
https://github.com/apache/incubator-guacamole-server
A month ago is after the point where Guacamole was accepted into the Apache Incubator, so there's a good change the code you cloned was actually closer to ~6 months old.
That said, even that old should be fine ... 0.9.9 happened before that and was a very decent release, and quite fast.
I should probably clarify that turbovnc runs without issues, it’s only guacamole.
Is there anything else you can tell us about your setup?
What does your network look like? What kind of machine is serving Guacamole? Are you using Tomcat or some other servlet container? Are there any proxies involved? etc.
You say that you're using a Guacamole-based tool. What differs here between the tool (what tool?) and a stock Guacamole deployment?
Any additional information about the deployment details of guac would be helpful.

Yes, I’ve tried a few browsers, chrome would actually dropout completely after a while and wouldn’t update my screen until I refreshed the page. Firefox performed the best, but it will still frustrating to use in comparison to turbovnc.
@Shashank: I’m currently in the process of re installing the entire setup on another machine, I will try to use a different vnc server once it’s complete.

Welcome Alex
VNC over Guacamole should be pretty fast, especially over LAN. Near or as fast as your TurboVNC client. Guacamole's first desktop/visual protocol was VNC after all.
Please specify what version of Guacamole you installed, on what server OS etc.., you may have outdated VNC library on your guacamole server. On Ubuntu thats libjpeg-turbo, for OS X Im not sure where that is to download.
See libJPEG-turbo in required deps:

RE: Guacamole Performance
Posted by Al...@csiro.au.
Hi Shanon,
I’m not sure about the version numbers but I cloned guacamole-client and guacamole-server directly from https://github.com/glyptodon about a month ago so it should be pretty recent. The guacamole server is running on debian 8.3. The libjpeg62-turbo and libjpeg62-turbo-dev libraries are up to date (according to apt-get)
I should probably clarify that turbovnc runs without issues, it’s only guacamole.

Welcome Alex
VNC over Guacamole should be pretty fast, especially over LAN. Near or as fast as your TurboVNC client. Guacamole's first desktop/visual protocol was VNC after all.
Please specify what version of Guacamole you installed, on what server OS etc.., you may have outdated VNC library on your guacamole server. On Ubuntu thats libjpeg-turbo, for OS X Im not sure where that is to download.
See libJPEG-turbo in required deps:

Hi,
I’ve recently installed a guacamole based tool to access remote machines. In comparison to using TurboVNC directly to the same machine, guacamole seems to perform very poorly (low fps, regular stutters, noticeable delay between input and feedback) and on safari some of the colours seem to be messed up. I’m just wondering is this possibly because I’ve set it up differently in some way to what it should be or if this is just the nature of the additional web layer on top of vnc?
Another small issue I’ve found is that the text becomes blurry if the browser stretches the resolution of the session. I try to set the size to be 100% (in the ctrl+alt+shit menu) but the minus button doesn’t let me go below 118% unless I resize my browser window)
