Hi,
I have installed the Patch and also made the GC setting change in STS.ini,
but still not much improvements. Switching between the files is still taking bit time..
I also observed that switching between java and property files is bit quick but switching between XML files in editor does take long time..
Not sure if I am the only one who is getting this kind of behavior.

I am running 2 instances of STS and only the instance which is bit loaded (6 projects and approx 2000+ files) is having this problem.
The other instance works well for XML switching but it has very less load (less than 50 files).

Please note I am not opening these thousands of files in the Editor when I mentioned the switching.. But just normal 20-30 files at a time.

Sorry, I haven't performed any memory monitoring exercise.
Thanks.
