Step 1 : Are the Ruby JRuby programs faster? At a glance.
This chart shows 3 comparisons - Time-used, Memory-used and Code-used.
Each chart bar shows, for one unidentified benchmark, how much the fastest Ruby JRuby program used compared to the fastest Ruby MRI program.
Step 2 : Are the Ruby JRuby programs faster? Approximately.
This table shows 3 comparisons - Time-used, Memory-used and Code-used.
Each table row shows, for one named benchmark, how much the fastest Ruby JRuby program used compared to the fastest Ruby MRI program.
