Eclipse performance issues

hi,

I'm using eclipse 3.5 with mylin and m2eclipse plugins with big projects and big workspaces.

These are my launch settings: (machine has 4Gig ram)

D:\eclipse35\eclipse.exe -vm "C:\Program Files\Java\jdk1.6.0_06\bin\javaw.exe" --vmargs -Xms1024m -Xmx1024m -Xmn256m -XX:PermSize=512m -XX:MaxPermSize=512m -Dide.gc=true -XX:+UseConcMarkSweepGC -XX:+ExplicitGCInvokesConcurrent -showLocation

But I've got a lot of performance issues, sometimes I can't use my pc for 15minutes, and it's got even worse since I'm using 3.5 and m2eclipse. (My anti-virus doesn't scan my workspaces)

If your PC is continously running, shut it down and restart it, then try your anti-virus program. If that doesn't help, you may have to re-install your Eclipse program.

Could it help by creating a new workspace? I use the same workspaces since 3.3
