I've spent the last few days messing with Linux in both VirtualBox and VMWare and I found that disabling 3D acceleration leads to ~2x faster boot, and disabling desktop compositing (in the Linux guest) leads to 5x less lag when moving things around on screen. I was surprised, because I thought using 3D acceleration and compositing would be faster. Also, I run the VM at half res and used DPI workaround (.manifest file) to let Windows scale the VM instead of VirtualBox (VirtualBox scaling is very slow for some reason).
