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.<o:p></o:p></span></font></p>
