That's what I surmised. > Please suggest is this ok ? As long as you have the RAM to hold that much heap (plus the other memory required by the process), it should be o.k. If you don't have at least 9 GB of RAM, you're going to be paging like mad, which will absolutely kill performance. Again, setting -Xss is usually pointless. I would set PermSize to the same value as MaxPermSize, just to avoid unnecessary expansion and contraction of the PermGen. > - Well we are using 64 bit JDK Which one? > - We are prinitng the heap mem using Log 4J utitiy in the > apllication logs. I don't know how log4j determines that value; what is shown by JConsole or LambdaProbe?
