Apache Tomcat settings

We have been seeing memory and CPU hit the ceiling with one of our Web servers..

Server Environment:
Windows 2003 (32-bit OS): on VMWare
Intel Xeon CPU: 2.67 GHz
3.75 GB RAM

Java: JDK 1.6.0_17 (yes, we are using the server version of the jvm.dll

Issue: CPU was pegging at 99% for extended periods..

CPU should never operate at over say 70% as we need a bit of overhead for OS other programs, etc.?
Currently, with the Java settings, we have currently set for Apache Tomcat:

-Dcatalina.home=C:\tomcat
-Dcatalina.base=C:\tomcat
-Djava.endorsed.dirs=C:\tomcat\endorsed
-Djava.io.tmpdir=C:\tomcat\temp
-Djava.util.logging.manager=org.apache.juli.ClassLoaderLogManager
-Djava.util.logging.config.file=C:\tomcat\conf\logging.properties
-XX:MaxPermSize=256m
-Xms1408m
-Xmx1408m
-XX:+UseParNewGC
-XX:+UseConcMarkSweepGC

Are there any recommendations that you can suggest from a best-practices and/or operational standpoint?

Thanks,

Kent

Do we have heavy traffic? Oh yeah.

Over 100 organizations use this server.

Then probably you want to move to a better and faster server, maybe some cluster

VMWare means that the same processor also serves other purposes ?

You probably want to have good dedicated server, and in my opinion Unix is more reliable system for such things

Yes.. At the minimum get on a 64-bit proc so we we can address over the 2GB memory space..

Agreed.

Thanks,

Yes, if so many people rely on it, it is definitely worth upgrading.
You'll hardly achieve anything substantial with any palliative measures.
