Hi Srinims, My experience is that Java seems to get unstable at about 70 threads (dependant on script). The thread switching within Java does not seem to be the best (i.e. you have limitations on Java). I'd go for Java 1.5.0_0x at least as it includes a lot of bugfixes.
Use Linux instead of Windows because Windows has too much overhead. It's OK to design your Jmeter tests on Windows and do trial runs but for execution I'd use some Unix. If the script is a little more complex (i.e. you load more than one static page) 220 threads is way too much. You will probably also notice that Jmeter (actually Java) will influence your response times significantly because the threads can't keep up and these delays are included in the measurements. What I did (under Linux) is start more than one jmeter server. The context switching of the OS is better than that of Java. i.e. run multiple Jmeter instances with about 50 threads each and then merge the test results after the test. You can't use the client/server option in Jmeter but you'll have to do this manually. This is based upon my experiences with Jmeter 2.1.1. I have not yet managed to run big tests on 2.2.

JVM is 1.4.2_03-b02. OS - WInXP with SP2 . The IIS server that I am hitting is on WIn2003 server box . Even with the current setting i.e 22 threads/sec for a 10mn duration tha max no of threads that could exist at the 10th minute is 220 which would never be the case bcoz some threads would have completed execution by then .I presume that my P4 machine (3 GHz) with 1 GB RAM could support at least 150-225 threads . srini -- View this message in context: http://www.nabble.com/Problem-with-Jmeter-tf2037855.html#a5614215 Sent from the JMeter - User forum at Nabble.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]
