I am using Jmeter to generate BOSH login, IM & Presence traffic to my presence server. The test is for 5000 users and the traffic from jmeter runs through a proxy server before going to the presence server. I have setup JMeter on 2 servers running 2 identical instances of my test scripts on each [2 x 2 x 1250 users/script = 5000 users]. The login period for 5000 uers is 20 mins after which time each user generates IM and Presence requests to the presence server. Everything is fine for the first 24 hours, I see a nice steady CPU rate of around 60 % on my presence server. However after 24 hours the CPU gradually gets larger and larger until the presence server's CPU reaches about 90% which is a test failure. I have checked my presence server logs and everything looks fine so the problem must lie with the toolboxes. Any idea what might be causing the CPU to rise gradually after 24 hours? Are there any memory configurations etc that need to be set prior to running a test? I am using a HeapSize of min: 256, max: 512 which for each instance. Do the NewSize values have to match these in terms of ratio? My toolboxes also contain 4 processors so I am tying each jmeter instance to a separate processor which seems to fix the problem intermittently. Any help would be much appreciated :-) -- View this message in context: http://old.nabble.com/Increasing-CPU-during-BOSH-Test-using-JMETER-tp28778525p28778525.html Sent from the JMeter - User mailing list archive at Nabble.com.
