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

The JMeter Wiki would be a suitable place...
