Publish Lambda benchmark script

Very cool project! Could the script that generated the benchmark screenshots in the README.md be publicised so we can run it ourselves? Or could the methodology section be updated as to how exactly we could reproduce it? Thanks!

Start with README.md, focusing on the benchmark screenshots and the methodology section. Determine whether the benchmark script can be published or whether the methodology can explain how to reproduce the results. Done means the script is publicly available or the documentation provides a reproducible procedure.
