    • 8. Personal notes• Very nice UI to manage• easy setup• pretty young (not too active mailing list/irc channel)• perfect fit for rails app since drop in replacement for memcache• We use it with dalli (https://github.com/mperham/dalli)• source compile is tough getting it right• is a mixture of many components (memcache, persistance engine, libevent, ns_server, erlang )• we use it as persistent memcache currently
