Step 1 : Are the Ruby JRuby programs faster? At a glance.
This chart shows 3 comparisons - Time-used, Memory-used and Code-used ~ speed and size.
Each chart bar shows, for one unidentified benchmark, how much the fastest Ruby JRuby program used compared to the fastest Ruby 1.9 program.
Look at speed another way - look at a box plot of Time-used data.
Step 2 : Are the Ruby JRuby programs faster? Approximately.
This table shows 3 comparisons - Time-used, Memory-used and Code-used ~ speed and size.
Each table row shows, for one named benchmark, how much the fastest Ruby JRuby program used compared to the fastest Ruby 1.9 program.

Step 3 : Are the Ruby JRuby programs faster? Measurements.
This table shows 5 measurements - CPU Time, Elapsed Time, Memory, Code and ≈ CPU Load ~ speed and size.
For each named benchmark, measurements of the fastest Ruby JRuby program are shown for comparison against measurements of the fastest Ruby 1.9 program.

Step 4 : Are there other Ruby JRuby programs for these benchmarks?
Remember - those are just the fastest Ruby JRuby and Ruby 1.9 programs measured on this OS/machine. Check if there are other implementations of these benchmark programs for Ruby JRuby.
Maybe one of those other Ruby JRuby programs is fastest on a different OS/machine.
Step 5 : Are there other faster programs for these benchmarks?
Remember - those are just the fastest Ruby JRuby and Ruby 1.9 programs measured on this OS/machine. Check if there are faster implementations of these benchmark programs for other programming languages.
Maybe one of those other programs is fastest on a different OS/machine.
