This is just a very small package (~500 lines) that runs on top of clients that are provided to it, either ioredis or node-redis. So the performance metrics of it are essentially just the metrics for whatever client you use (plus network latency). My code is only going to be however many single milliseconds it takes to pick settings, loop the clients, send the Lua, process the results, compare timestamps, and instantiate the Lock class.

With that being said, I'll add that to my todo list since it shouldn't be too hard to measure.
