1 : Are the OCaml programs faster? At a glance.
Each chart bar shows, for one unidentified benchmark, how much the fastest OCaml program used compared to the fastest C++ g++ program.
These are not the only compilers and interpreters. These are not the only programs that could be written. These are not the only tasks that could be solved. These are just 10 tiny examples.
2 : Are the OCaml programs faster? Approximately.
Each table row shows, for one named benchmark, how much the fastest OCaml program used compared to the fastest C++ g++ program.

3 : Are the OCaml programs faster? Measurements.
These are not the only tasks that could be solved. These are just 10 tiny examples. These are not the only compilers and interpreters. These are not the only programs that could be written.
For each named benchmark, measurements of the fastest OCaml program are shown for comparison against measurements of the fastest C++ g++ program.

4 : Are there other OCaml programs for these benchmarks?
Remember - those are just the fastest OCaml and C++ g++ programs measured on this OS/machine. Check if there are other implementations of these benchmark programs for OCaml.
Maybe one of those other OCaml programs is fastest on a different OS/machine.
