Howdy Folks,
I've got a pretty interesting 4-node cluster on 2 servers (each server has 2x900+ P3 CPUs and 2GB of RAM). Each startup server has the following Heap Allocation $ java hotspot -Xms800m -Xmx800m -XX:SurvivorRation=2 -XX:NewSize=128m -XX:MaxNewSize=128m. I use the default of 15 for my thread count and beyond that, I don't really do anything else.

I'm using HotSpot with JDK 1.3 in my start-up server file. I've seen some other tuning parameters from the http://java.sun.com/products/hotspot/2.0/README.html web site, but never implemented any. Performance is just average (acceptable), but for my hardware and configuration, this environment should be humming with no problems. Anyone have any JVM/Hotspot performance tips?
Steve

If you are not using the VM that BEA provides then be sure you are using the server hotspot to run weblogic. There is a difference, the client is the default on Win platforms which since you say P3, I guess you are on.
