Quoting redis docs (http://redis.io/topics/benchmarks http://redis.io/topics/benchmarks): > When the server and client benchmark programs run on the same box, both the TCP/IP loopback and unix domain sockets can be used. Depending on the platform, unix domain sockets can achieve around 50% more throughput than the TCP/IP loopback (on Linux for instance). The default behavior of redis-benchmark is to use the TCP/IP loopback. Haven't measured myself though.
