Individual VM CPU
There may be variability in the numbers that is not captured in these tests, as this was a small sample. Red bars represent the Hyper-V environment and blue bars represent VMware in all the following graphs, and time is in seconds – so the lower the better.
The first individual test I ran is a single CPU running a single process and there
is a little bit of an anomaly shown here, as surprisingly Win7 on Hyper-V
appears slower.
I ran the single process
with an extra vCPU and didn't see any negative impacts, no degraded
performance but it didn't help either.
I then ran twice the amount of work in the same time using two
processes.
Summary of CPU results
To summarize
·
Windows CPU performance on Hyper-V was significantly
slower
·
Two vCPUs running a single process had little negative
impact.
On Wednesday I'll show the results for an Individual
VM Disk.
