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

Try to profile Netbeans using VisualVM. If the "hot spot" is org.gnome.accessibility.atkwrapper.emitsignal(), try to run Netbeans with

-J-Djavax.accessibility.assistive_technologies=" "

It helped a lot in my case.

I don't really know why exactly this toolkit used, but looks like it's generally safe to disable it.
