To know the version may be interesting but not really useful, I bet that if you change Redis with a dummy TCP server that is only able to reply +OK, whatever it receives, you'll get the same numbers here.

Basically every kind of networked server with a simple request-response protocol, in a busy loop over loopback, will show performances between 10k and 20k requests per second, mostly up to the speed of the implementation of the client.
