# Enhancing virtual machine performance
|
|
|
|
In virtual environments, the cache server egress peaks at around 1.1 Gbps. If you want to maximize the egress in virtual environments, it's critical to change two settings.
|
|
|
|
## Virtual machine settings
|
|
|
|
Change the following settings to maximize the egress in virtual environments:
|
|
|
|
1. Enable **Single Root I/O Virtualization (SR-IOV)** in the following three locations:
|
|
|
|
- The BIOS of the MCC virtual machine
|
|
- The network card properties of the MCC virtual machine
|
|
- The hypervisor for the MCC virtual machine
|
|
|
|
Microsoft has found these settings to double egress when using a Microsoft Hyper-V deployment.
|
|
|
|
2. Enable high performance in the BIOS instead of energy savings. Microsoft has found this setting to also nearly double egress in a Microsoft Hyper-V deployment.
