Also one thing about OS X running in VMWare is make sure you're using the specific CPU to the fullest potential. Graphics are rendered with the use of CPU. If you don't have the processor(s) / cores set properly you could be only at 50% overall performance. For example, I am currently using an i3 330UM. I've noticed a significant jump in performance switching from single processor 2 cores; to 2 processors 4 cores.
Personally, Mavericks outperformed Yosemite on this little machine. I've experienced long window load times, hangs, and even guest crashes since the jump... My main desktop workstation is rocking an i7-930; I WILL NOT upgrade my main VMWare workstation to Yosemite. If I need to I will just clone my current VMWare image and run Mavericks / Yosemite in tandem. I would much prefer Mavericks > Yosemite...
