Step 1 : Are the Ruby MRI 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 MRI program used compared to the fastest Perl program.
Step 2 : Are the Ruby MRI 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 MRI program used compared to the fastest Perl program.

± read the measurements and then read the program source code.
Step 3 : Are the Ruby MRI programs faster? Measurements.
This table shows 5 measurements - CPU Time, Elapsed Time, Memory, Code and ~ CPU Load.
For each named benchmark, measurements of the fastest Ruby MRI program are shown for comparison against measurements of the fastest Perl program.
