Charles, My client has installed two instances of tomcat (each as a service). I'm not really sure how they did it (they have the standard C:/Program Files/Apache Group/Tomcat 4.1 folder, but the apps and conf files are in D:/instances/instance1/conf, D:/instances/instance1/app, D:/instances/instance1/work, D:/instances/instance1/log). I'll talk to the guy who configured this so I can emulate one of the instances in batch mode. I'll let you know how it goes after I make the changes!

Yes, tomcat is running as a service. You might want to shutdown that service and run it from a command-line window, at least for testing purposes. Easier to fiddle with heap size options and the like. > 2. I am not aware of any CPU affinity settings. They won't show up in Task Manager. Not sure if the plain Windows Server supports affinity; my experience with that capability was on a 32-CPU Advanced (Enterprise?) Server system which I no longer have access to. There's an mmc plug in Admin Tools that lets you play with associating processes with CPUs, if it's available in your OS. > 3. I'm not sure what options are set with the jvm (I didn't > install the service). IIRC, the default heap size for the 1.4.1 JVM on Windows is only 64 MB, and that's really not enough for any serious work. I suspect that you're spending much of your time in garbage collection. - Chuck THIS COMMUNICATION MAY CONTAIN CONFIDENTIAL AND/OR OTHERWISE PROPRIETARY MATERIAL and is thus for use only by the intended recipient.
