If you are using iSCSI as storage connection you can win a lot of performance by enabling jumbo frames. It is important that your Storage, Switch and Network Card do support the use of jumbo frames.
Now if all parts do support jumbo frames you have to enable this on your network adapters.
First you have to enable this for the operating system. This is very simple done with the netsh command line tool.
netsh int ipv4 set subint "Interface Name" mtu=9000 store=persistent
Now if you are Intel network cards you have to enable jumbo frames in the registry.
Here you can see all of your network interfaces and you can simply change the “*jumbopacket” value to 9014.
If you don’t now which network interfaces are the iSCSI interfaces you can check the interface GUID here:

Recently I posted about a page in the TechNet Wiki which lists a lot of Hyper-V tools. Yesterday on Hyper-V workshop, Michel Lüscher mentioned two lists in the TechNet Wiki where you can find Hyper-V and Cluster Hotfixes for Windows Server 2008 R2.

Microsoft and the community are really starting to work with the TechNet Wiki platform. Now thanks to James van den Berg I found a great wiki page with a collection of Hyper-V tools.
The collection includes a list of the following content:
- Supported Microsoft Tools (Solution Accelerators, Product Downloads, etc.)
- Microsoft Products and Solutions that are Built upon Hyper-V Technology
- Remote Management from Client Versions of Windows
- Unsupported Microsoft Tools (Sysinternals, MSDN/ScriptCenter Code Galleries, TechNet/MSDN Blogs)
- Community Tools (CodePlex and blogs)
- Third-party Free Tools
- Hardware-Specific Tools from OEMs and Vendors
- Partner Solutions (Commercially Available)
- Application-specific Performance Planning/Testing/Analysis tools
You can find also a lot of other interessting content on the TechNet Wiki. For example for Exchange, PowerShell and SQL.
