 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.

Ruby MRI used what fraction? used how many times more?
Benchmark	Time	Memory	Code	Reduced N
binary-trees	±	±	±
regex-dna	±	2×	1/2
reverse-complement	2×	1/2	±
spectral-norm	2×	1/3	1/3
fasta	2×	78×	±
n-body	2×	±	±
fannkuch	3×	±	±
mandelbrot	3×	1/2	±
pidigits	4×	4×	±
k-nucleotide	4×	1/5	±

± 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.
