My file ~/.netbeans/6.9/etc/netbeans.conf on my Mac laptop contains:
# options used by netbeans launcher by default, can be overridden by
# command line switches
netbeans_default_options="-J-Xms256m -J-Xmx768m -J-XX:PermSize=32m -J-
XX:MaxPermSize=160m -J-Xverify:none -J-
Dapple.laf.useScreenMenuBar=true -J-XX:+UseConcMarkSweepGC -J-XX:
+CMSClassUnloadingEnabled -J-XX:+CMSPermGenSweepingEnabled -J-
But sometimes the reason NetBeans is slow is because by default it is
scanning every source file, but
usually that only happens when the project is opened, once.
I'd need more information as to what part of NetBeans you think is slow.
