I am running Fusion 5 on 10.8 and it works great. Now I want to upgrade my 2010 Mac Pro to Mavericks and Fusion 6. However, a friend of mine is running Fusion 6 with a Win XP VM on Mavericks and he says it's almost unusable. The WM now takes about 5 minutes to boot, and everything is then extremely slow. However, he is using this combo on a 2.4GHz MacBook Pro with 4GB RAM from 2007. Could this be the reason why it's so slow? But he says everything worked perfectly before upgrading to Mavericks.
Could I have the same experience on my Mac Pro? Is anyone running Win XP and Win 7 in Fusion 6 on Mavericks with same or better speed as on 10.8?
