Hat-tip to Ben for this one.
If you’re interested in the kind of things that can impact performance within Virtual Machines, from a networking perspective, and how you can optimise accordingly, this article may be of use to you. In a nutshell, increasing the VMBus buffer size within the VM, can increase network throughput to guest VMs, in some cases, very significantly indeed. Obviously it relates to your environment, and the workloads generating the network loads, but it’s definitely worth a read.
There are a number of useful suggestions in the article, along with how to make the changes.
That’s the networking done, but don’t forget about the Performance and Tuning Guidelines for Windows Server 2008 R2 that I told you about a week or so back too. All useful stuff!
