Eclipse 3.5 64-bit Performance Windows 7

Question

I installed Eclipse Galileo and after trouble with the JDK, its starting well. But I have big problems with performance. Every third second, Eclipse is hanging for a while. It runs not smoothly. I need a efficient IDE as Eclipse for work. So, it would be very nice when you have a fast answer :)

Both Eclipse as the JDK are 64-bit versions.

Have you any ideas?

Update:

I can´t really explain the problem from scratch. But in my case, it was a trouble between Eclipse´s and the auto-complete-function of my OSK. If I disabled auto-complete, there was no hangs anymore. I don't know why the using of the OSK blocks the thread (?) of the whole editor.

Maybe anyone of you, has an idea why?

Answer 1

From your description it sounds like the garbage collector is being triggered. How much RAM have you got in the system? Depending on the plugins you're loading Eclipse can need quite a lot of it. I think the bare minimum is 256 Mb, and realistically you need at least 1 Gb, more if you're doing web development

Have you got an up-to-date JVM? Eclipse generally runs much quicker with a 1.6 JVM.

One other thing to check, do you have an aggressive virus scanner? Eclipse plugins are collections of small files in jars, some virus scanners can really slow down the performance. If you are able, remove the Eclipse install directory from the scanned files.

See this EclipseZone article or this question for some general performance tips.
