Is there a recommended configuration for virtual disks in Hyper-V? I have a virtual machine that I set up recently running 6.2 that has *very* slow disk performance. It took well over an hour to untar ports.tar.gz. The host server is a few years old, but it's running 3 RAID-5 7200rpm drives, quad-core Xeon and 32 GB RAM... so not exactly a slow machine. And this is the only Hyper-V VM it's hosting.
I've got the virtual disk configured as IDE / VHDX / Expanding (the Hyper-V defaults). The controller can be IDE or SCSI. The disk format can be VHD or VHDX. And the disk can be configured as fixed or expanding. I'm going to try converting the disk to fixed and defragging my NTFS. Any thoughts on IDE vs SCSI and VHD vs VHDX?
