This is pretty hard to answer. Depends a lot on how good of a filesystem
cache your os has, and if you have enough memory on the clients to support
The big win for memcached is that requests are split over the farm. So
the more front ends you need, the bigger your cache. (Depending on the
bottlenecks on your backend, maybe you want to run memcached on the
backend machines too...)
If you've only got one front end, and you already have some sort of
caching mechanism, memcached isn't going to help

Success! You are foaf http://openid.enslaves.us/
