Another note to self…
If your PC (mac or whatever crap u have there :P) has 1gb of ram use following flags when running eclipse:
-vmargs -Xms512m -Xmx512m -XX:PermSize=128m -XX:MaxPermSize=128m
If you have any more ram on your setup replace 512 with [amount of ram]/2 and 128 with [amount of ram]/4 and you will get decent results.
PS.
