These numbers are running JRuby interpreted. Here's the actual numbers. tl;dr: JRuby is generally faster. The cases that aren't, I probably haven't looked at optimizing.

Also, the benchmark/ips included in Rubinius does not do a separate warmup before running actual numbers, so later results can be skewed. Minor detail, though.
