If you are only running one server, you might be better off using APC
for your caching. If you have 2 servers, you might get better
performance by running your PHP on both, and also using both for
memcache (with memcache the more physical servers you have, the
faster it can go, on average). This will also give you a bit of
redundancy, letting your service continue if one server dies.
