Hyper-V High Physical Disk queue on guest system

Hi,

I'm having an issue about high physical disk average write and read
queues on one of my Windows 2003 guest runing ISA 2006.

The same queues on host system are ok, mostly below 1.

Anyone have a tip to me ?

Thanks for your time.

Check and see if it's paging that's causing the read/writes, and if it
is, allocate more RAM to the VM.

The Paging is in another volume/VHD as well as ISA, the disk with high
physical disk average write and read queues is the system volume C:.

The VM has 4GB memory and isn't using it all.

Thanks for your time.

Interesting.

You can probably figure out what is doing the I/O via this:

But you might want to ask in an ISA forum too...
