Don't get too excited. This is a micro-benchmark and not representative of what most real world apps will see. A benchmark of something the scope of a typical rails app is likely to be much much less. Earlier descriptions of MJIT mention benchmark tests that were only ~11% improvement until the benchmark was "tuned" for the JIT. [1] If you're modifying the the benchmark specifically for the JIT, it's not really a valid benchmark IMHO.
