Load Testing

Posted by Matt Sat, 09 Jun 2007 00:32:53 GMT

This week I get to load test our J2EE application with JMeter. I'm running JBoss on my Dad's old powerbook -- G3 500MHz, 512 MB RAM. I ran the tests with 100 concurrent users. Here's something you don't see all that often :

bosworth@rout:/usr/local/jboss/server/pws/log$ w
06:18:03 up 69 days, 21:14, 2 users, load average: 73.64, 42.36, 23.98
USER TTY FROM LOGIN@ IDLE JCPU PCPU WHAT
bosworth tty1 - 16Apr07 20:26 0.79s 0.65s -bash
bosworth pts/0 flee.lan 06:02 3.00s 0.65s 0.03s w

73.64! Yikes! No errors though....

Update: Here's the results with 300 concurrent :

bosworth@rout:/usr/local/jboss/server/pws/log$ w
06:53:09 up 69 days, 21:49, 2 users, load average: 17.90, 99.05, 114.98
USER TTY FROM LOGIN@ IDLE JCPU PCPU WHAT
bosworth tty1 - 16Apr07 21:01 0.79s 0.65s -bash
bosworth pts/0 flee.lan 06:02 1.00s 0.68s 0.03s w

Still no errors! Go little Mac, go!
