My client needs to improve the performance of their WAN. They have three sites spread som 600 km apart with roughly 400 users per site. It's mainly a Microsoft environment.

Today they are using Windows XP clients and Windows Server 2003 (and some 2008 R2)

They have done a pilot with a 3rd party WAN accelerator and performance increase was good but it did not work as transparently as they wished for.

Since this is a Microsoft shop I want to recommend them to upgrade clients to Windows 7 and servers to Windows Server 2008 R2 and enable branche cache.

But I have no experience of my own with branchecache and thus I am asking everyone here at ServerFault, what is your experience of using Microsoft BranchCache to optimize WAN performance?

It looks like BranchCache caches web and file content. Is that going to be enough? What about email, databases, etc.? – joeqwerty Jun 20 '11 at 10:39

Why not also consider a branchcache pilot for some additional custom fitting and analysis?
