No one's trying it on the developer end so far as I know... The speedup here is about libevent's built in httpd. Using a new buffer interface/etc. Memcached wouldn't be using any of that, as it's already doing optimized IO internally. Unless you're bigger than facebook, odds are you'll be fine with libevent 1.4 and the default threadcount with memcached. -Dormando
