 Step 1 : Are the OCaml 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 OCaml program used compared to the fastest C++ GNU g++ program.

 Step 2 : Are the OCaml 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 OCaml program used compared to the fastest C++ GNU g++ program.

OCaml used what fraction? used how many times more?
Benchmark	Time	Memory	Code	Reduced N
fannkuch	±	±	1/2
regex-dna	2×	4×	1/2
n-body	2×	±	±
spectral-norm	2×	2×	1/3
pidigits	2×	2×	±
reverse-complement	2×	2×	1/4
mandelbrot	3×	2×	±

fasta	6×	±	±
k-nucleotide	8×	4×	1/3
chameneos-redux	17×	±	±

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

 Step 3 : Are the OCaml 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 OCaml program are shown for comparison against measurements of the fastest C++ GNU g++ program.
