Has anyone used memcache UDP on PHP using the pecl module "memcache" or "memcached"?
I'm already seeing quite a bit of improvement by using the binary protocol over ascii, but I'm trying to push the envelope further and see if I can squeeze some more performance by using UDP. Are there any downsides to using UDP? I remember reading something about facebook using UDP, but having work with data/packet loss as UDP is stateless. Is this handled by the PHP module?
