1 : Are the Ruby JRuby programs faster? At a glance.
Each chart bar shows, for one unidentified benchmark, how much the fastest Ruby JRuby program used compared to the fastest Ruby 2.0 program.
These are not the only compilers and interpreters. These are not the only programs that could be written. These are not the only tasks that could be solved. These are just 10 tiny examples.
2 : Are the Ruby JRuby programs faster? Approximately.
Each table row shows, for one named benchmark, how much the fastest Ruby JRuby program used compared to the fastest Ruby 2.0 program.

3 : Are the Ruby JRuby programs faster? Measurements.
These are not the only tasks that could be solved. These are just 10 tiny examples. These are not the only compilers and interpreters. These are not the only programs that could be written.
For each named benchmark, measurements of the fastest Ruby JRuby program are shown for comparison against measurements of the fastest Ruby 2.0 program.

4 : Are there other Ruby JRuby programs for these benchmarks?
Remember - those are just the fastest Ruby JRuby and Ruby 2.0 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.
