Heya, I've given a MXDU presentation on that stuff in 2005 (<http://www.bloginblack.de/archives/000630.cfm>) - Slide 34 actually has a few good references to read up on the topic if you like.
Basically - I can't agree more to Stephen - JVM settings can ruin your performance if done wrongly and they can improve your performance as soon as your systems architecture derives from the standard environment. Not sure which JVM you're on, here's another good read for 1.4.2: <http://java.sun.com/docs/hotspot/gc1.4.2/> Cheers Kai >On May 12, 12:07 pm, "Steve Onnis" <[EMAIL PROTECTED]> wrote: >> Can someone shed some light on what the JVM Heap Size is actually meant to >> do?
