IMO, it must be a _very_ small system to max out on 2-3 threads. What OS/RAM/JVM are you using?
[We did find that JMeter client-server mode was quite slow, but that was largely because of network traffic over a WAN.] Might be worth trying batch (non-gui) mode - some JVMs don't have very efficient GUI implementations. == As to generating the 32 bit (? - should that be byte?) alphanumeric string, you could generate one or more files with the strings in them, and then use _StringFromFile() to read the value into a parameter which you can use later in the script. The Javascript function could probably generate longer numbers too. Depends on what you want.

With 2-3 threads on my smallest machine, jmeter-server maxed out the CPU, while ApacheBench could run with 1000 concurrent requests. Admitedly, this was a very small machine and is not representative of the hardware I'll be using to run the actual tests. It _did_ give me a good comparison between AB and JMeter. At first it appeared as though the stress test would be simple GETs, but I just learned that for each "session" (1 get of this page, 5 gets of that one, and 10 of another) I must supply a unique 32 bit alpha-numeric parameter in each request. ApacheBench cannot do this, so I'll have to use JMeter. I've found a couple of decent size servers I can use, so it shouldn't be too bad. My problem will be generating that 32 bit string. The "Counter" pre-processor certainly won't be enough. Do you have any suggestions? :) Thanks! js. -- Jean-Sebastien Morisset, Sr. UNIX Administrator <[EMAIL PROTECTED]> Personal Home Page <http://jsmoriss.mvlan.net/> JS & Melanie's Homebrewery <http://brewery.mvlan.net/> Underwater and Travel Photographs <http://www.mvpix.com/> --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
