The community is awesome to provide feedback about quality and features. The comments left to the previous entry, made me improve the NetBeans Module Startup Settings I am developing.
1) a drop-down with presets of jvm parameters
2) library of jvm options with a short description for each one
3) links to performance related websites

NetBeans IDE as a pure Java Swing app, can use any JVM parameters, it can be specified at netbeans.conf file, as Charlie Hunt blogged about that, see NetBeans IDE: Adding/Changing JVM command line args. Then as Charlie asked to contribute a plugin to configure NetBeans startup settings, I decided to try it, an developed the plugin, see a small screenshot below (click to enlarge).
