Mountain Lion works very slowly in VMware 8. XCode 4.5 is terribly slow. I tried the following things to speed things up:

  1. Installed VMware tools from darwin.iso provided with the vmdk file of MacOSX.
  2. Turned off desktop animations, minimization animation etc.
  3. Allocated 3GB of RAM for the VM.
  4. Increased no. of processors to 4.

However, the virtual machine is still too slow. What are the ways to speed things up other than the ones I mentioned above? The only apps I need to run in Lion are: XCode and Iphone simulator. It's ok if the techniques speed up only those two apps.

I wouldn't expect much if you're running it on Windows. OS X doesn't run particularly well as a virtual machine on OS X, and that's with the optimizations that are coded in to VMWare Fusion. Running on VMware Workstation is totally unsupported, probably required some hacking just to get it running, and IMO you're on your own. –  gabedwrds Oct 21 '12 at 2:43
In fact, any optimization technique that would work on mac should work on vm. Example: the technique discussed here: stackoverflow.com/a/6356862/1122681 works and does improve the performance of XCode. –  Robik Oct 21 '12 at 3:57
Yes, anything that helps on a real machine should also help in a VM, and so you may get some genuine tips. I'm just pointing out that the VM is still going to be the #1 performance problem. –  gabedwrds Oct 21 '12 at 4:07
Yes. Since I don't have a Mac now, I will have to work with VM. Are there developers who do this? or is it too inconvenient? –  Robik Oct 21 '12 at 6:07
It is inconvenient as well as illegal. Apple doesn’t allow you to run OS X in a VM on a non-Apple computer. You can run OS X in a VM on a Mac, by the way. –  duci9y Oct 21 '12 at 6:14

For better video performance. MAke sure RAM is Half of the Total amount of RAM your System Uses. Also Mac OS X Runs best with 2 Processors. Also download VMsvga Driver which helps with Video Preformance.

Where can the VMsvga driver be downloaded from? –  patrix Jan 11 at 14:59
