I'm revisiting this thread after a few years but this is an issue I'm sure someone must have gotten to and knows the solution, I'm running solaris2.10, JDK 1.5.0_06 or 1.5.0_11 (32 bit or 64 bit), both are really slow. JBoss takes up a long time to come up and I'm running load test using JMeter and the system response time for each query is 800-900ms as suppose to 100ms on the linux box. root@benchmark # psrinfo 0 on-line since 05/24/2007 17:11:31 1 on-line since 05/24/2007 17:11:32 2 on-line since 05/24/2007 17:11:32 3 on-line since 05/24/2007 17:11:32 4 on-line since 05/24/2007 17:11:32 5 on-line since 05/24/2007 17:11:32 6 on-line since 05/24/2007 17:11:32 7 on-line since 05/24/2007 17:11:32 8 on-line since 05/24/2007 17:11:32 9 on-line since 05/24/2007 17:11:32 10 on-line since 05/24/2007 17:11:32 11 on-line since 05/24/2007 17:11:32 12 on-line since 05/24/2007 17:11:32 13 on-line since 05/24/2007 17:11:32 14 on-line since 05/24/2007 17:11:32 15 on-line since 05/24/2007 17:11:32 View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4048702#...
