We have a recent and up2date Linux Redhat installation, and the sun Java hotspot 1.4.2 in server mode JVM. When I run "top" I see Java as one process, and with one Tomcat running in a performance test, it only hits 50% CPU (of a 2 CPU box). When I run 2 tomcats, I see two processes, and it hits 100% CPU. If anyone has seen this behavior, and then changed some settings to get Tomcat or Java to use multiple CPUs for one instance, I would be curious. Maybe it is something with the threading model or something. I thought Java used native threads by default, or at least green threads on top of native threads (one-to-one), so Im not sure how this fits in...
