Hi Sreejith,

Could you make available your manual to the JMeter community?

Also, are there any difference in performance results between JMeter and
Loadrunner i.e. Do they provide results that are consistent with each
other?

Subject: Re: need information about JMeter

Hi,

I had the oppertunity to use both Mercury Loadrunner and JMeter, during 
different times in my career.LR is a commercial tool while JMeter is a 
freeware. JMeter does most of the stuff LR does, but there is slight
learning 
curve in getting it set up and run. Loadrunner gives a built-in recorder
which 
can record a script and you can have placeholders for your params that
you need 
to pass/receive back. JMeter uses an HTTP proxy , which has to be set up
for 
this. LR has a browser simulation which is closer to the actual thing,
but in 
JMeter, you need a Tree Listener , which is somewhat like a bare minimum

browser. You can do away with less of tweaking in LR but you need to
know 
Regular Expressions to extract and reuse variables in JMeter. In fact,
the 
better you know Regex, better mastery you have over JMeter. LR gives you
a 
controller module to tun your tests where you can pick and choose your
flows. 
It is easy to parameterize your scripts and to setup your runtime params
in LR 
as they have GUI widgets for all this. JMeter gives you the same
functionality 
but it is more of adding a listener and tweaking it. I guess I read LR
manuals 
on an 'as needed' basis where I had a manual handy for JMeter. LR gives
you an 
option of mix and match scripts at the same time - which is a real life 
scenario. I am yet to figure out how to do this on JMeter. JMeter
integrates 
well with ant, which makes it a good developer's tool. I should add that
it was 
a good learning experience to work on JMeter, as you may have to
interact with 
the user groups to figure out things. Also, framing of reports is much
more 
intuitive in LR where as JMeter uses listeners for the same
functionality.

These are the things that are on the top of my head. Pls let me know if
you are 
looking for anything specific.

regards

sreejith
