I agree that maxing out 512 seems high. Looking at my currently running Tomcat servers, here's my usage:
Server 1 -- 1 Tap4, 2 Tap3 -- Heap 140 MB, PermGen 85 MB Server 2 -- 2 Tap3 -- Heap 134 MB, PermGen 35 MB Server 3 -- 5 Tap3 -- Heap 59 MB, PermGen 46 MB Server 4 (leaky) -- 1 Tap3 -- Heap 610 MB, PermGen 25 MB The above apps are all running Hibernate except for Server 4. I normally allocate 512 to both heap and permgen, although as you can see I don't really need that much. Server 1 and 2 get the most traffic, also with close to 100 concurrent users.
