 Step 1 : Are the Perl programs faster? At a glance.

This chart shows 3 comparisons - Time-used, Memory-used and Code-used ~ speed and size.

Each chart bar shows, for one unidentified benchmark, how much the fastest Perl program used compared to the fastest Java 7 -server program.

Look at speed another way - look at a box plot of Time-used data.

 Step 2 : Are the Perl programs faster? Approximately.

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

Each table row shows, for one named benchmark, how much the fastest Perl program used compared to the fastest Java 7 -server program.

Perl used what fraction? used how many times more?
Benchmark	Time	Memory	Code
pidigits	±	1/14	1/5
regex-dna	±	1/5	1/2
reverse-complement	2×	±	1/6
k-nucleotide	9×	5×	1/4
spectral-norm	65×	1/2	±
fasta	66×	1/7	1/2

binary-trees	78×	1/2	1/2
mandelbrot	123×	±	±

Perl used what fraction? used how many times more?
Time-used	|-	|---	25%	median	75%	---|	-|
(Elapsed secs)	±	±	2×	66×	78×	187×	187×

± 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 ~ speed and size.

For each named benchmark, measurements of the fastest Perl program are shown for comparison against measurements of the fastest Java 7 -server program.

 Step 4 : Are there other Perl programs for these benchmarks?

Remember - those are just the fastest Perl and Java 7 -server programs measured on this OS/machine. Check if there are other implementations of these benchmark programs for Perl.

Maybe one of those other Perl programs is fastest on a different OS/machine.

 Step 5 : Are there other faster programs for these benchmarks?

Remember - those are just the fastest Perl and Java 7 -server programs measured on this OS/machine. Check if there are faster implementations of these benchmark programs for other programming languages.
