vSphere vs Hyper-V showdown - CPU details

The following set of charts show some metrics from both platforms that I collected using athene to use on an ongoing basis for my capacity management.

Hyper-V is dark blue and vSphere light blue, shown side by side.


 
CPU metrics
Some metrics that are worth monitoring, how much time the virtual CPU is waiting for a ‘slice’ of the physical CPU:
 
·        vSphere VM ready time
·        Hyper-V Guest run time 
 
CPU Details - vSphere CPU Ready Time
 
All 4 machines were running and I chose to view them as a stacked chart.
 
 
You can see from the graph how it ‘spiked’ however the reality is that this is being viewed by percentage, so they weren’t actually waiting for too long.
 
CPU Details - Hyper-V Guest Run Time
 
This is a single metric guest run time.
 
 
One interesting feature is that this spiked up over 100% on two occasions.
 
On Wednesday I’ve selected three memory metrics for each platform and we’ll be taking a look at those.
