Research from Principled Technologies suggests that a large UNIX/RISC-based, business-critical database application handling peaks of 10,000 queries per hour is delivering good performance. Using that metric, Principled Technologies set about testing 12 VMs hosted on a server running VMware vSphere 5.0 using the Intel Xeon E7 processor family.

How did it handle? According to Principled Technologies, "this solution comfortably supported 12 80GB databases" without over-committing resources and allowing all VMs to run in parallel with solid performance.
