I'm trying to figure out how large of a heap size I can set for my LCDS tomcat nodes before I start to see GC performance problems. We are running 64-bit everything, so theoretical limits aren't a problem. We are currently running 2GB.
Is anybody running more than 2GB? If so, how much and do you ever see problems with long GCs (or any other issues)? Anybody know a reason why I couldn't run 4GB?
