 Step 1 : Are the Perl 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 Perl program used compared to the fastest Java 6 -server program.

 Step 2 : Are the Perl 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 Perl program used compared to the fastest Java 6 -server program.

Perl used what fraction? used how many times more?
Benchmark	Time	Memory	Code	Reduced N
pidigits	±	1/5	1/2
regex-dna	2×	1/4	1/2
reverse-complement	2×	±	1/2
k-nucleotide	4×	2×	1/4
fannkuch	37×	1/8	1/3
fasta	37×	1/6	±
spectral-norm	66×	±	2×
n-body	71×	1/6	±
binary-trees	80×	2×	±
mandelbrot	106×	1/16	1/3

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

 Step 3 : Are the Perl 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 Perl program are shown for comparison against measurements of the fastest Java 6 -server program.
