So I just got this (running in VMWare Player), and it's pretty slick but damn does it give my computer a workout. Just sitting there with xchat open and nothing else going on, I'm at 36% CPU utilization. On the other hand, with Ubuntu 12.04 running in a VM I'm at 4% CPU utilization. Has anyone else noticed Mint doing this, or is this just me?
And no, I haven't, but I don't really look much at my CPU usage on Mint and I also don't run it on a VM. It shouldn't really make much difference because although Mint runs Cinnamon while Ubuntu runs Unity, I doubt there's that much, if any difference in performance between the two, and I don't see what else would be running on Mint that could account for it. You could take a look at the output of 'top' in the terminal to see what processes are using so much of the CPU.
