Giving XP additional CPU power?

I'm using a XP installment to play World of Warcraft (yes, I know it exists for OSX).
While it runs fine to begin with, after awhile it gets real choppy. However, OSX is still running fine, without any slowdowns or anything.

Would it be possible to set a higher priority for XP so it can handle WoW better?

 

Well, you can only give one core to Parallels...
But, inside of your configuration window you can find a setting to optimize for Guest OS performance, a setting to increase VRAM, and a setting to increase allocated RAM.

 

Yeah I know. However I think that the bottleneck in my case is the CPU.
Have 1200mb ram allocated for XP, that should be more than enough for casual wow playing.

 

What does the Task Manager and Activity Monitor show as CPU usage?

 

WoW uses 90-99% in XP
And activity monitor says parallels uses about 110% (?) when WoW is running

 

It sounds like the core that Windows XP is getting is maxed out. Parallels does not support multiple-cores being used by a VM.

 

WoW shouldn't really use that much resources, I think.
Must be somekind of efficiency problem. But what do I know.

 

Well, you could compare the CPU usage to a real pc.
