Rebol ÷ Perl | Computer Language Benchmarks Game

Step 1 : Are the Rebol 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 Rebol program used compared to the fastest Perl program.

This table shows 3 comparisons - Time-used, Memory-used and Code-used.

Each table row shows, for one named benchmark, how much the fastest Rebol program used compared to the fastest Perl program.

Rebol used what fraction? used how many times more?
Benchmark	Time	Memory	Code	Reduced N
recursive	3×	4×	±	3
spectral-norm	4×	3×	2×	3,000
sum-file	4×	335×	2×
mandelbrot	5×	4×	2×
nsieve	6×	±	±
fannkuch	7×	4×	±
binary-trees	7×	2×	±
n-body	8×	±	±
fasta	8×	4×	±
reverse-complement	66×	±	±
k-nucleotide	192×	±	3×	100,000

± read the measurements and then read the program source code.

This table shows 5 measurements - CPU Time, Elapsed Time, Memory, Code and ~ CPU Load.

For each named benchmark, measurements of the fastest Rebol program are shown for comparison against measurements of the fastest Perl program.
