Is Eclipse Slow for you?

Over the course of the last few months, my Eclipse has become very slow to open. From what I noticed, it was the FlexBuilder plugin pieces causing the delay. Fortunately, it turned out to be my fault.

The trick to speed up Eclipse? Close the Projects you aren't using! I had over 60 open projects. By selecting the project, Right-Clicking and choosing 'Close Project' this seems to help a lot. You can select and close a bunch of projects at the same time. Very nice indeed when closing 60+ projects.

Of course, select the closed project, right-click and choose 'Open Project' when you wish to work with the contents of the project.

From 1.5 minutes start up to < 20 seconds... I am a happy man.

Also, you can close Open Perspectives by right-clicking on the perspective (in the top right-hand corner) and choosing 'close'. This works well for less commonly used perspectives like SQLExplorer and the like.

Thanks, buddy. This has been a headache for me for the past 4 months. I have tried all sorts of memory tweaks with no luck. This finally did the trick!

I am using Eclipse, and experiencing many problems: (1) It is very large. (2) It is very slow. (3) It has a lot of bugs. (4) Due to safety measures, I cannot have Java Runtime in my workstation.

Somebody told me about another editor, Emacs. It is quite large (47 M installation package). However, if I eliminate things that I don't use, Emacs can be reduced to less than 3 Megabytes.

I would like to know how to reduce Eclipse to less than, say, 5 Megabyte. I also don't want to have the Java Run Time, since it is very large, and slow. Is it possible to compile Eclipse in less than 5M, using a native code generating compiler, so I don't need Java VM? I need only four languages: Simplified Chinese, Polytonic Greek, English, and Ancient Egyptian. I program only in LISP and Prolog. Therefore I don't need Java.

Thank you for answering.

I'm afraid it isn't possible to use the Eclipse editor without Java. Eclipse must have java in order to function. This is one of the reasons why it is slower than other editors. Another reason is Eclipse has been designed to have lots of integrations and plugins, each of which add their own slowness.

However, there are a few editors you may want to look at if speed and size are issues.

Notepad++ is a free (as in "free speech" and also as in "free beer") source code editor and Notepad replacement that supports several languages. Running in the MS Windows environment, its use is governed by GPL License.

Sublime Editor:
Sublime Text is a sophisticated text editor for code, html and prose. You'll love the slick user interface and extraordinary features.

Let me know if either of those work for you...
