@PopeDai: IO is also a problem for me. I have a server that does heavy image processing, and I can see the CPU and memory well within my tolerance, but disk access is pegged. This also probably also has something to do with our crappy SAN.

I'll also note that the new Task Manager in Windows 8 only measures IO throughput when it calculates % utilization. I find that IO-operations-per-second pose a much bigger threat to system responsiveness than a long sequential write. Maybe I'll file a bug on this...
