How to improve Netbeans performance?

Question

Is there a real way to get Netbeans to load and work faster?

It is too slow and gets worse when you have been coding for some time. It eats all my RAM.

Simplest solution:

Go to Preferences->Editor and Disable: Auto Popup Completion Window

Use: Meta key + \ instead when you need code completion.

The biggest problem I found was the auto code completion feature. As I typed, it kept on trying to run code completion the whole time. This was causing really slow performance since my project has a lot of libraries that it depends upon.

The best thing of all is you can stop fighting the editor as it keeps picking up false positives in the completion popup.

Have not looked back since I switched this off.
