We are troubleshooting disk performance issues on a Hyper-V terminal server running 2012 R2. User are complaining that programs can be incredibly slow to open, will be intermittent. Used by about 6 users as there main desktop. Runs accounting programs, outlook and office programs, some file sync and share, other general use stuff. Current Disk Queue Length seems to average around 6 during the day with spikes in the 11-22 range and one off highs of 86. Avg. Disk sec/Write averages 41ms yesterday and seem to sit in the 60ms range during the day. This is all monitored from the Hosts drive where the VHDxs are stored.
