query on bandwidth connection
Hi all,
I have recorded a transaction of a web application with 100MBPS connection, now i want to execute the same transaction with different Dail up speed like 128,256,512kbps.
Is there any option or element in jmeter so that i can provide this various speed and execute for different Vusers.
Thanks in advance

Just realised that the calculation of the delays only works for small
values of cps - below a few K - I'll fix that later.

The nightly code now has an option to set up a Slow Socket for the
HttpClient Sampler.
See jmeter.properties for details.

Re: query on bandwidth connection

I've now had a look at the HttpClient code, and posted a question on
the mailing list - it appears that one can register a new
ProtocolSocketFactory, and use that to return a "slow" Socket. Not yet
sure if this is in 2.0.2, or only in 3.0.
Rather than enable this feature via an extra GUI item, I assume it
would be sufficient to switch the code on via a property, so it will
apply to the entire JMeter testplan.

Here is a link to an old thread on /. about simulating different kinds of
traffic, it might save you some time.

I did some research into this a few months back for fun. There is a low
level network driver that can simulate dropped and corrupt packets, but
using it would be tricky. One would have to install the driver on the server
and configure it properly. Then running a test from JMeter would be the
same.

Hi
Thanks for the reply Sebb and Peter i will search for the network driver and try to work on it

One can add delays to the scripts, but the connections will still only
be active for short periods of time, so as far as the server is
concerned it will appear to be the user who is slow, rather than the
network.
One really needs to be able to slow down the actual network reads/writes.
This does not appear to be possible at present using either the
default JVM or Apache HttpClient implementations, as neither gives
access to the underlying connection. I'm looking into this further.
I suppose one could use a separate proxy to do the slowing down; not
sure if there any suitable applications.

currently that is not possible with JMeter. Measuring the performance on a
variety of connections like dial-up, dsl, cable modem and T1 is actually
rather hard to do. Mercury has the ability to simulate lower bandwidth, but
I don't know how "accurate" it is. dail-up connections are notorious for
dropped packets, so the only real way to measure real world performance is
to get a couple dozen dial-up accounts and test the website.
