You can try out in-memory nosql db named tarantool (http://tarantool.org/)
with replication functionality, which suports memcached protocol.

Some little bit changes:
Using the fact that dispatcher keep balance between threads while
dispatch new connections, we can move out freelist into conn_queue
without any problem with unbalanced size of free items on each
conn_queue. Also I eliminate tailing "while .. free" code in cq_push

I suggest you to eliminate taking of the lock on cqi_freelist.
In order to it we should done all work on cqi_freelist by one thread
-- dispatcher thread in memcached.
I made some changes in queue code, including improvements for cache
line.
It will work on any platform.
There are patch file (diff -
I found in thread.c:109
pthread_cond_signal(&cq->cond);
without any waiting for that condition variable.
I don't know, will it helpful if you eliminate using it.
