vSphere vs Hyper-V performance showdown - Key Performance Metrics

I'll start the comparison this week with a list of the key performance metrics that are advisable to look at for capacity and performance management, although these are only a very small sub-set of the actual metrics available to you.

 

vSphere

                         

CPU

Avg. CPU Usage in MHz

CPU Ready Time

 

Memory

Avg. Memory Usage in KB

Balloon KB

Swap Used KB

Consumed

Active

 

I/O

Queue Latency

Kernel Latency

Device Latency

 

Hyper-V

 

CPU

Hypervisor Logical Processor % Hypervisor Virtual Processor %

Memory

Dynamic Memory Balancer

Dynamic Memory Pressure

VM Vid Partition

 

 

I/O

Virtual Storage Device

Virtual Network Adapter

 

Knowing how and when these metrics change is imperative to evaluating the system being tested, and we will look at these in more detail further on.

 

VMware data comes in through the vCenter and Hyper-V has a set of metrics available through perfmon (Hyper-V makes dynamic memory metrics available after adding service pack 1)

 

On Wednesday I'll be dealing with the challenges you face in benchmarking virtual environments.
