Hi! Load testing my application ( with Jboss 3.0.8 ) I had these strange results:
If using 1 jboss node, with cluster settings active but without another machine, I runned a test scenario that consisted of 10, 100 and 200 users navigating through my site. I had this batch file that would do "run 10x scenario with 10 users, then run 10x scenario with 100 users, then run 10x scenario with 200 users" I left this running over night, and got the results in the next day... Then I added the second machine, with similar settings, to the cluster. I went home and left my batch test running... 50% of load to each machine. Each machine would see the load corresponding to the following batch test: "run 10x scenario with 5 users, then run 10x scenario with 50 users, then run 10x scenario with 100 users" (which would total a cluster load the same as above) Well... my test client locked soon after beginning the 50 users test... there were exceptions thrown in JBoss because of "out of memory" errors... I changed my java memeory settings by using "%JAVA%" -Xmx384m %JAVA_OPTS% in my run.bat file. I went home once again, confident that now it would work... I rerun the "10x 50users + 10x 100users" test When I got back... it was locked soon after starting the 100 users test, with exceptions on JBoss and the memory usage (measured by windows task manager) was over 400Mb... Well, I rerun the 100 users test, and it eventually locked again, exceptions and memory usage again over 400Mb after running 5x the 100 users test... While I've not reached a conclusion, these questions are bothering me: - Why did the batch rest run completely when there was only 1 machine, without exceeding the standard (128, right?) Mb memory usage? - Why do I triple the memory available to java and it still goes to maximum usage, and after hours of not loading the server the memory usage does not decrease? - Could I set more aggressive memory settings to java that could free more memory, making my app work without the "out of memory"? -- Joao Clemente - jpcl at rnl ist utl pt ------------------------------------------------------- This sf.net email is sponsored by:ThinkGeek Welcome to geek heaven. http://thinkgeek.com/sf _______________________________________________ JBoss-user mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/jboss-user
