I'm trying to load-test my web application. I am using a thread group with 100 threads, ramp-up: 0secs, repeat: 10. When I ran this test the GUI becomes non-responsive and the CPU and memory usage go to 100% utilization. This is on a 1.2GHz CPU with 378MB (with less then 200MB used with normal apps opened).
Using top I get: PID USER PRI NI SIZE RSS SHARE STAT %CPU %MEM TIME COMMAND 12633 grom 20 0 147M 147M 16188 R 79.7 39.1 2:11 java 13544 root 14 0 1220 1220 816 R 11.9 0.3 0:02 top 2451 grom 9 0 7224 6104 4172 S 1.8 1.5 1:06 gnome-terminal 1425 root 6 -10 281M 20M 7912 S < 1.3 5.3 7:30 X 12639 grom 9 0 147M 147M 16188 S 0.4 39.1 0:03 java 13432 grom 9 0 147M 147M 16188 S 0.3 39.1 0:00 java 13460 grom 9 0 148M 148M 16188 S 0.3 39.2 0:00 java 13481 grom 9 0 148M 148M 16188 S 0.3 39.2 0:00 java 13213 apache 9 0 4736 4736 4520 S 0.1 1.2 0:00 httpd 13216 apache 9 0 4736 4736 4520 S 0.1 1.2 0:00 httpd 13227 apache 9 0 4648 4648 4472 S 0.1 1.2 0:00 httpd 13248 apache 9 0 4736 4736 4520 S 0.1 1.2 0:00 httpd 13414 grom 9 0 147M 147M 16188 S 0.1 39.1 0:00 java 13417 grom 9 0 147M 147M 16188 S 0.1 39.1 0:00 java 13419 grom 9 0 147M 147M 16188 S 0.1 39.1 0:00 java 13421 grom 9 0 147M 147M 16188 S 0.1 39.1 0:00 java 13423 grom 9 0 147M 147M 16188 S 0.1 39.1 0:00 java I added "-Xmx256m -Xss2m" options to the jmeter startup script. But I had similar results before this. What is going on??? I have seen in the archive people posting results such as "I've executed 100 threads in a single thread group on a Dell laptop with 256M Ram and a 800Mhz processor with no problems." Olav Groehn posted >>>>>>>>>>>>>>>>>>>>>>> Usually a PC can handle quite a big number of threads without problems but think about some other effects that might result in wrong measurements of server response times: A good idea is to monitor the workload of your CPU. If it is around 100% it might be to much meaning your CPU is overloaded and the measured response times might be incorrect. >>>>>>>>>>>>>>>>>>>>>>>>>>>>> I also look at using distributed testing. I run rmiregistry as follows $ export CLASSPATH=/usr/java/jakarta-jmeter/lib/ext/ApacheJMeter_core.jar:/usr/java/jakarta-jmeter/lib/jorphan.jar:/usr/java/jakarta-jmeter/lib/logkit-1.0.1.jar $ rmiregistry then in another terminal I start the jmeter-server script. Then from a different machine I start the client, but when I try to remote start the test plan it doesn't seem to do anything. Yet, the access logs indicate that it was accessed.
