Slow save in Eclipse

My saves got slow after installing egit. I uninstalled this, and things are back to normal.

To tell you what solved the problem: We installed Eclipse 3.6 and there we turned on system processed in Process View. Above process System: Updating status for Tomcat... stood process Calculating Decorations.

We turned off all decoration, except SVN decoration (Window-Preferences-Label decorations) and saving works fine now.

Apparently there is some limit in number of files of project above which Eclipse is behave strange?
