Very surprising. I have 4Gigs of Ram in my MBP and I am using VMWare to virtualize a windowsXP box. I allocated it 1.5 Gig of RAM. With the last VMWare upgrades, it became slow, very slow, incredibly slow. No changes to my configuration but boot took twice more time, mouse was so slow I found it unusable at times, and globally my user experience became awful. This morning, I decided to tweak just a very little bit my config:

  • if I change the allocated RAM to 1016Megs of RAM, I am back at full speed.
  • if I set it above 1024Megs of RAM, for instance 1036, boom things become hyper-slow again.

Honestly, this is a very painful issue and I count it as a bug...
