Hi Joe,
"Another useful tip would be to turn on incremental garbage collection. This is always good to free up unused portions of memory that haven't been used for a significant time interval." Where can I find this feature to turn it on ?

The golden rule for sizing tomcat memory is to not use more than 65% to 70% of the available free memory before the tomcat service is started. This gives the server at least 30% to 35% headroom. With that in mind it is nice to have a max memory of at least around the 3 GB mark where the usage of the servers is about average. Since you are using tomcat, if you are using Mid-Tier 7.1, I would recommend to hop on the patch 006. In my experience here the earlier patches had a memory issue, that addresses OutOfMemory errors that cause Tomcat to crash which was addressed in Patch 006. Also the performance is way better as I have noticed that it takes a relatively short time for the server to build its cache after an initial restart on patch 006 (at least 5 to 10 times faster) than it was on lets say Patch 003. I haven't tried patches in between 003 and 006 Hope this helps..

We are windows 2003 and we have two mid tiers that are load balanced.
