I tried 32M once and that worked. The only app I had installed was a simple web service. Maximum? That depends on the OS and whether you are running a 32-bit or 64-bit JVM. A Windows 32-bit JVM is usually limited to 1.5-1.7G, while on Linux it is around 2G. For a 64-bit JVM the virtual limit is very high (around 2^64 bytes) but the practical limit is based on the amount of available memory (RAM + pagefile) with the recommended limit being the amount of free RAM. -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/561466#561466] Start a new discussion in Performance Tuning at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&...]

But it depends to you application and the used GarbageCollector stategie what is useful. -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/561610#561610] Start a new discussion in Performance Tuning at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&...]
