While not uncommon, the performance variation of most of these virtualized instances is so high that your numbers are probably within the range of acceptable error. (For reference, I have a team that does nothing but maintain a performance benchmarking harness and test lab, so i know these things pretty cold :P) I also don't see that the benchmarks were even run multiple times. I tried to follow the ruby-benchmark-suite all the way down the rabbit hole, but don't see anywhere it runs benchmarks multiple times, let alone gives you the variability, etc.
