Jeff, I had the same issue with scheduled tasks having a IO priority of "low". I posted the solution here:

Seeing that the I/O prioritization for scheduled tasks is to Low by default, is there any way to override this? I have lots for FTP scheduled tasks that transfer slow on 2k8 then they do on 2k3.

Hi. We have the same identical issue as Doug. 2008R2 machine acting as a DC DNS and HyperV Host the machine is stable until we start a 2003 Guest then over time the memory creeps up until the Server Crashes. Has any one found a fix for this?

We are experiencing what appears to be a Memory Leakage issue with Win 2008R2 running as a Hyper-visor. If the machine is just left idle with no Virtual Machines running, it maintains a pretty steady 1-1.5Gb "In Use" memory status. As soon as we start a Virtual Win2003 Server 1024Mb Machine the "In Use will jump to an understandable 2-2.5Gb "In Use". However, over time this will grow and continue to grow until the Hyper-visor Server locks up.

Anyone else experiencing this?

SuperFetch was a service found in Server 2008 but it is apparently gone in R2. If true, what are the implications of this -- is it a feature now built into the OS? Removed as not necessary? Replaced by another technology?

thanks for the article...
