Java on Multi/Dual Core
Hi,
I apologize for this question, maybe the wrong place to put it to. But someone who is using Tomcat soon or later will be confronted with the performance problem with java and multi/dual core machines. Multi/dual core is trendy, customers want to have it. But Java runs slower on these machine, what will make them angry.
I've not seen any useful information about the JVM of Sun Version 1.4 in any forum yet.
Have anyone experience on this topic with JVM from Sun above 1.4 (used by us until now), i.e 1.5 or 1.6, or maybe any IBM JVM?

If you have a single threaded application, some of the old single
core machines may be quicker than a new multi-core machine.
You must have a pretty strange version of tomcat to run 'single'
threaded...
Compiling is a different matter, as it seems Sun's JVM (1.4, 1.5)
only uses one core - JRocket is quicker there...
