AppFabric vs Unity vs Memcached or possibly any other multi server caching mechanisms

Question

Hi,

I am currently in the process of investigating the various different caching mechanisms out there whether they be free or at some cost (minimal preferably).

The situation. Currently we have to load-balanced servers that host our web application with a third server being an SQL server. This site is a eShop, and it gets hit quite regularly at large volumes.

I have been asked to research the caching mechanisms of Memcached and Unity from MS, but in the process have come across AppFabric as well.

Can any one please tell me what for the above scenario is the best caching mechanism?

We are currently using the .net caching mechanism with ASP.Net and we are also aware of the Enterprise Library Caching system.

Thanks.
