go-redis
A redis implementation in Go.
Thanks to US Airways treating me to an unexpected 9 hour layover at PHL, I found myself with a little extra time, so I hit the bar and decided to see if I could implement a Go server implementing the redis protocol and GET/SET commands.
I spend probably 2 - 3 hours on this, and the result is kind of neat, as it seems to perform almost as well as redis itself without attempting any forms of optimizations yet.
Given that I'm now stuck at BRU, I'll probably implement this in node.js as well for comparison. To be continued ...
Running
go run main.go

The numbers below should give you a rough idea, but don't take the numbers too seriously as I've not done any extensive analysis here.
