Incredibly slow deletion of files in windows 7 64bit ultimate

using shift-delete to remove large numbers of files from win7 directories can take hours.. the CPU is not working, the drive is active but not excessively so (its a SAS RAID5 4 drives).

Deleting from the command prompt doesn't improve performance.. however, copy and creation of new files is perfectly speedy (Using a caching RAID controller)

At a complete loss to figure this out.. hell I may even have to go to microsoft if noone here can help...

in summary..
tried del /s /q *.*
writes files just fine
moves files to the recycle bin much faster then a straight delete.

Consistent across drives (the system drive is RAID 1 and suffers as badly)

The RAID 1 may be the culprit. Everything has to happen twice in this configuration. The create operation is quick because the next space on the disk is used. The deletes have to take into account all of the places on the disk the file(s) may reside, paging.

Hardware raid 1 tests out as no slower than a single drive (15krpm sas drive) and the problem exists on raid 5, raid 1 and a spplememtal test today occurs on a SATA 2TB seagate.

Have you tried deleting via an elevated administrative command line?
START | cmd.exe | RIGHT-click on cmd.exe | select "Run as Administrator"
