Benchmarks addition to readme

Thanks for creating this, i really love the API

I feel it would be great if you could add benchmark results to the readme.. Even better if you could add this library's benchmark tests here https://github.com/rs/logbench this runs benchmarks for several structured loggers and the stats is always upto date.

Thanks in advance!
