In the resource monitor I'am looking at the disk response time. There are a lot of processes where the response time is thousands of milliseconds consistently, I'm pretty sure this is the source of my computer slowing down. I'm not sure what normal response times are though?

I'm running win 7 64bit ultimate. This is running on a new computer, i5 with a terabyte drive, 4gigs of ram, etc, disk is still pretty much empty, so it should all be pretty snappy.

And if it is going really slow, how do I track down whats causing it?

I've turned off things like real time virus protection as experiments to see if there is something weird there, but makes no real difference (other than it doesn't contribute to the problem by accessing the disk)
