Wow! This is advanced stuff! I have not done anything for the JVM tuning yet--so I imagine everything is at its default value now. Time to dig in and see what I can do with them... We have 4 CF 8 instances running on one (pretty powerful) virtual server. So far there has been no performance issues, but I am sure there is room for improvement!
