hi..

from the time when i click right click on a property of a project it takes a while (half a minute) for it to show or focusing on eclipse again does the same thing.
in visualvm i see that in these seconds there is constant garbage collection between eden and survivor 0 and survivor 1, meaning eden graphs fills up, dumps to s0 then fills up again and dumps s1 and fills again and dumps to s0.
what's going on?

Probably you have got your VM settings wrong. Whats is your
OS/JVM/Eclipse build id/VM settings?
