I have couple of suggestions to Carsten and Unico: http://blog.reverycodes.com/archives/000028.html
Anything else I forgot? :)
For me, when Eclipse (the new stuff) was trying to 'decorate' all files with the SVN status, it killed my machine. I've found Eclipse 3.x fat as all heck without extra junk like that.
Hmm, that said, I've toyed with som many combinations of these two I wonder if that is an historical problem. I now get the latest Subclipse from loonsoft, using Eclipse updates, and don't seem to have the same problem. It saved me cycles for a while though...

Adam
