Poor virtual machine application performance may be caused by processor power management settings
Issue
- Virtual machine application/network performance is poor when compared to another host.
- Applications run slower than expected. When they are moved to another host, performance improves.
- Virtual machines encounter higher than expected CPU %Ready times in ESXTOP.
- Processor Power Management (Power Saving, Power Scaling) is impacting application performance on virtual machines.
Environment
- HP ProLiant servers with the HP Power Profile option (ProLiant G6 or greater)
- HP ProLiant servers without the HP Power Profile option
- Dell PowerEdge 11th Generation servers with BIOS
- Dell PowerEdge 12th Generation servers with UEFI BIOS
