Nikita, With that hardware you will hit problems running much more than 256 threads. The problem being that the context switching between the threads starts to choke the bus and cache and you find that JMeter run erratically.
I normally use a 3.6GHz P4 with hyperthreading. 384 is the max threads it will take before I am measuring JMeter's performance rather than that of the of server ;-) If you are not using Keep-Alive, then you also should look into the max user port in your registry settings. Otherwise you are likely to run out of user ports on your test machine. See support.microsoft.com/kb/314053 Also, it rather depends on how complex your test is. Nice simple HTTP Samplers are OK, but if you have assertions and regex extractors in there, you will see the limit coming in faster.

Hi, Just wondering what is the max possible number of *client* connections were people able to generate concurrently using JMeter? My load-generating machine is: Intel Pentium M 2.13Ghz, 2GB RAM, WinXP. If I play w/ JVM -X settings what number of threads can I expect JMeter to be able to run simultaneously (I'm assuming JMeter isn't using NIO so 1 thread = 1 client cxn). Should I expect 100s or 1000s of threads? thanks -nikita --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] -- No virus found in this incoming message.
