ocamlprof: The OCaml profiler


ocamlprof - The OCaml profiler


ocamlprof [ options ] filename ...


The ocamlprof command prints execution counts gathered during the execution of a OCaml program instrumented with ocamlcp(1).

It produces a source listing of the program modules given as arguments where execution counts have been inserted as comments. For instance,

ocamlprof foo.ml

prints the source code for the foo module, with comments indicating how many times the functions in this module have been called. Naturally, this information is accurate only if the source file has not been modified since the profiling execution took place.
