 Step 1 : Are the Haskell GHC 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 Haskell GHC program used compared to the fastest OCaml program.


 Step 2 : Are the Haskell GHC 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 Haskell GHC program used compared to the fastest OCaml program.

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

 Step 3 : Are the Haskell GHC 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 Haskell GHC program are shown for comparison against measurements of the fastest OCaml program.

 Step 4 : Are there other Haskell GHC programs for these benchmarks?

Remember - those are just the fastest Haskell GHC and OCaml programs measured on this OS/machine. Check if there are other implementations of these benchmark programs for Haskell GHC.

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

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

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

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