I'm running the 64 bit JDK on my laptop but I've only begun to compile
programs on it so I don't know much about performance differences. I

more performance.
Is more CPU usage a good thing? Is there a noticeable performance
It's a web server processing the exact same # of requests as before.
It was running into GC pause / OOM issues before when we were limited to a
1.2 GB heap by the 32 bit JDK. And yes, the real issue is to cache (or more
exactly clear caches) properly but that's harder to solve :-)
So we switched
ive been running a big-ish webapp (both in development and production) on a
64bit JVM for about a month and have not noticed such dramatic performance
drop. But them again, im not running windows nor using compressedOOPs -
maybe its one of those?
