This comparison doesn't make even a hint of sense. If an in-program LRU
cache is adequate for your use case, don't look at memcached.

If you need your resident cache set to be (much) larger than the amount
of RAM in your machine, or you need machine redundancy, or you need to
distribute rather than replicate the cache, then memcached is the right
