Description Jiri Rechtacek 2012-03-19 11:40:42 UTC

Since NetBeans 7.2 provides 64-bit launcher for Windows (http://hg.netbeans.org/main-golden/rev/34fef02e9b05) we can balance -XX:MaxPermSize according to what version JVM is running.

Proposal:
Windows 32-bit - _no change_
-Xmx is RAM/5, min 96m, max 384m
-XX:MaxPermSize is 256m

Windows 64-bit - 64-bit JVM  _no change_
-Xmx is RAM/5, min 96m, max 768m
-XX:MaxPermSize is 384m

Windows 64-bit - 32-bit JVM  _decreased_
-Xmx is RAM/5, min 96m, max 384m (previously max 768m)
-XX:MaxPermSize is 256m (previously 384m)

On Linux - _no change_:
-Xmx is RAM/5, min 96m, max 768m
-XX:MaxPermSize is 384m
