Netbeans Performance Switches

I recently have began to use Netbeans because I'm sad that Eclipse is every time slower and it frozes every time when you are doing something to fast.

Netbeans is not perfect, and there are some features that need to be polished (Ex.: SVN Support, Time Tracking like Mylyn), but the PHP/HTML/CSS/JS Support is excellent, in my opinion better than the Eclipse PDF support.

These is my netbeans_default_options for Netbeans for MacOSX (under Windows you can leave out the --laf switch, it's for changing the look and feel):

netbeans_default_options="-J-client -J-Xss2m -J-Xms32m -J-Xmx512m -J-XX:PermSize=32m -J-XX:MaxPermSize=200m -J-Xverify:none -J-XX:CompileThreshold=100 -XX:+CompressedOOPS -XX:+AggressiveOpts -XX:+TieredCompilation -XX:+DoEscapeAnalysis -XX:+UseConcMarkSweepGC -J-XX:+CMSClassUnloadingEnabled -J-XX:+CMSPermGenSweepingEnabled -J-Dapple.laf.useScreenMenuBar=true -J-Dsun.java2d.noddraw=true --laf javax.swing.plaf.metal.MetalLookAndFeel"

Some switches come from Netbeans Performance site.

  • -J-Xss2m - Define Stack Size (Too small and you will get StackOverflow Exceptions)

Eclipse Configuration for Web Development

After trying very different IDE and many Eclipse IDE flawors, this is the best configuration I have found, and all the components are free.

First of all we need to download Eclipse Classic from the Eclipse website.

One of the first things we need to do is to change eclipse.ini, we will make it start faster and increase the memory limit

--launcher.XXMaxPermSize
256m
-vm
/usr/bin/java
-vmargs
-Xms40m
-Xmx1024m

The path to Java VM depends on your installation and system, in windows you must search for "javaw.exe". Setting the path to Java VM makes that Eclipse stops searching for the Java VM every start, which makes the start faster.

Now we can start installing the required Plugins. In "Help->Install New Software..." we will add the following Update Sites.
