I have a VM in which doing large file deletes is incredibly slow. It was originally on our SAN and I moved it to local storage, but the issue remains. Large groups of small files seem to be the worst. But right now I have a delete of 3,500 files (235mb) and it is estimated at 3.5hrs to complete (will probably take longer). It doesn't hang entirely, it does move. Disk IO is at nothing and file copies are fine. I am at a loss for what this could be. We have file servers that we do deletes on, no problem. The VMs were all made from the same 2008 R2 template.
Any ideas?
