Subject Tomcat problem on a multiple CPU system
Date Sun, 04 May 2008 20:21:57 GMT


I have a 2x quad core (8 cpu units) server.


If I start a java program and this one is launching (at the same time) 8
thread doing some CPU intensive jobs, all the CPU are used at 100%, and
that's what I'm expecting..


But, if I am using tomcat, and I call a servlet 8 times to process these
8 jobs, it take longer to execute these same 8 jobs and all the CPU are
not used at 100%, it's more like 30%...


Any idea about this problem or behavior ? I'm using Tomcat 5.5.17,
windows, JDK 1.6
