Change JVM parameters for NetBeans

To change the JVM parameters for NetBeans so that it runs better (in case you have hardware), go to Netbeans installation directory and find the netbeans.conf file inside the /etc dir:

C:\NetBeans-7.0.1\etc\netbeans.conf

Open the file netbeans.conf and find netbeans_default line:

netbeans_default_options="-J-server -J-Xss4m -J-Xms256m -J-XX:PermSize=64m -J-Dapple.laf.useScreenMenuBar=true -J-Dapple.awt.graphics.UseQuartz=true -J-Dsun.java2d.noddraw=true -J-Duser.language=en -J-Duser.region=US"

I changed mine to include some additional JVM parameters. Also, note that I changed the mode from -client to -server (it runs better in my notebook's hardware I guess :-).

So the new JVM parameters are:

-J-server -J-Xms128m -J-Xmx512m -J-XX:+UseConcMarkSweepGC -J-XX:+UseParNewGC -J-XX:ParallelGCThreads=4 -J-XX:+CMSParallelRemarkEnabled -J-XX:NewSize=64m -J-XX:MaxNewSize=64m -J-XX:+DisableExplicitGC -J-XX:PermSize=64m -J-XX:MaxPermSize=256m

The complete line:

netbeans_default_options="-J-server -J-Xms128m -J-Xmx512m -J-XX:+UseConcMarkSweepGC -J-XX:+UseParNewGC -J-XX:ParallelGCThreads=4 -J-XX:+CMSParallelRemarkEnabled -J-XX:NewSize=64m -J-XX:MaxNewSize=64m -J-XX:+DisableExplicitGC -J-XX:PermSize=64m -J-XX:MaxPermSize=256m -J-Dapple.laf.useScreenMenuBar=true -J-Dapple.awt.graphics.UseQuartz=true -J-Dsun.java2d.noddraw=true -J-Duser.language=en -J-Duser.region=US"

Enjoy the better performance! :-D
