These numbers seem off. 4ms to store something in memory ? Even if it include network latency it should be able to improve further.

  Most of the bottleneck is in the TCP stack. That's why user mode networking like this module does helps a lot.

    TCP latency is on the order of dozens of us, not ms. Valid question I'd say.

      TCP latency increases when you have high load and buffers in the way. Over 50% of CPU time is spent in the TCP stack for Redis, with the bulk of the rest in query parsing.
