First I would like to congratulate the JMeter team for creating a great tool that is getting even better everyday. Secondly I could use some help on one minor issue. . . I seemed to have hit a bottleneck with repect to the number of simultaneous threads that can be generated using Jmeter1.7 (march 18 nightly build ) on my clients Load testing workstation (win2K, 128MbRAM 800Mhz P3). Can't get past 50 threads without the machine locking up on me and/or my sampling times go from milliseconds to minutes. I have tried a number of tricks learned both from past experience and from reading news groups, mail archives, the jdk 1.3.1 docs etc. So far the only noticeable improvement has come from bumping the heap size up from the java command line. That is in fact how I got the number of threads up from 40 to 50. If any of you java magicians out there have OS and/or java config tricks up your sleeve that might help me get this number up to 100-500 threads please let me know. In the meantime my next course of action is to try and setup the jmeter server on the solaris 220s where the web servers live and just using the testing station as a client. Although this is a different test entirely, I would expect to see a dramatic improvement in the number of simutaneous users Thanks. -David-
