This may be a bit too obvious, but the one time I saw a similar thing, it was something as silly as making a new connection to memcached each time.
I had some wrapping functionality that had a typo in it that caused it to drop its connection to memcached and reconnect for every get. I've also seen some funny things on some redhats doing dns resolving when that server also happens to be a dns server. Thats the only real configuration issue I can think of. Make sure you have the latest stable libevent installed, and configured to be the most optimal for your system.. Can you provide a sample of your code we can look at, that may give us more clues.
