Having been asked by @headius to re-run the previous benchmarks with a single concurrency to get a measure of the raw processing speed of the different VMs. The results are below, and are quite surprising, in my opinion.
I have to say I did not expect REE, Ruby Enterprise Edition, to come out on top. Possibly that isn’t too surprising, as it has superior Garbage Collection, compared to MRI. Once again, Rubinius was not as strong as I would have expected, which is leading me to believe that I am not a master of the Rubinius – if anyone knows any ways to force Rubinius to precompile or use something like JRuby’s —server flag, I’d appreciate it!
