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.

Answer 1

I've decided to research for last time why my NetBeans was running slow.

I am running PC with 16GB ram and 3.5GHz 8 Core Processor. My CPU usage is around 5-20%, memory is below 40% yet NetBeans is slower than my 15-year-old PC that I have stashed in the garage.

After finding this topic and going through http://wiki.netbeans.org/FaqSlowNetBeans I have realised that in the bottom right corner of the NetBeans I keep seeing a bar that states "Scanning...", after trying to stop it and nothing happening I have looked further at what "Scanning..." was doing and I have realised:

Each time I start the NetBeans, the NetBeans will automatically scan any open projects.

And here it is, I've closed 20 opened projects and NetBeans runs as fast as Notepad.
