They might not be swapping, but they certainly appear to be spending a
good amount of time on GC. 0.8sec for an incremental GC is significant.
But that might be because your heap is so high.
>RAM is 4GB. Any attempt
Hi, thanks for the insights.
I've done what you suggested, and the load does look better, but still sluggish.
The machine's are not swapping, simply JVM's max memory is 2GB. Our
RAM is 4GB. Any attempt to assign larger max memory to java, will
cause failure in starting tomcat. A friend has tried d
n access? If not precompiling, you have beefy iron
but enough restarts and that is a lot of cycles at peak.

Pure FUD. You need to specify the jsr77Names="true" attribute to the
ServerLifecyleListener to have TC 4 JMX register the servlet
you're option is to back port the status servlet to tomcat4. if you
manage to do that, it should work I would think :) If you do, I will

Yup, upgrade.
Then tune solaris (/etc/system) and the TCP settings via ndd. The TCP
