VMWare Snapshot Performance Hit?
Posted on 2015-01-14
I am using snapshots for VMs before I run Windows updates on them, as these past few months have been really bad for Microsoft updates. Lots of potential for RGEs. Anyway. I am wondering, in a scenario where you have a couple (2 or 3) of VMs running on a single physical 7200 RPM hard drive, how bad of a performance hit will these VMs have if I leave them running on a snapshot for a few days? IE no more than a week. I just want to leave some time to suss out any problems these updates may have before I delete the snapshot.
Do you think a week is fine for hard drive IO?
