Very cool project! I'd suggest before running the new benchmarks to reach out to to the developers of the packages you are testing against to see if they think the benchmark you wrote is doing efficient calling conventions. I work on a large open source software project and we've had people claim they are 10x faster than us while they were really using our code in some very malformed ways.
Also stops them from grumbling after you post good results!
