Boost TFS Performance under a VM

According to Andrew Dugdell, one of the VM Gurus, in order to boost your TFS performance under a VM you have to read the following 7 (non-desctructive and quite simple) tips.

1. Move your VM to a second physical disk to your host OS – maybe even a USB drive if you are on a workstation or Laptop
2. Defragment the filesystem inside your VM
3. Defrag the pagefile inside your VM – Sysinternals PageDefrag works a treat
4. Defrag the drive on your host that holds the VHD
5. Defrag the pagefile on your host as well – again pagedefrag from sysinternals
6. Install [updated] VM Additions inside your VM – latest version is 13.552
7. Configure your anti-virus scanning to exclude VHD files on the host
