Questions tagged [gprof]

gprof is a GNU tool used for code profiling.

To use it you need to compile your code with gcc and the option -pg. Then execute your software; it will create a file named "gmon.out". gprof can analyze this file and provide you with performance information about the execution of your software.

Tools for profiling OCaml code

Is anybody aware of programs for profiling OCaml code apart from using the -p option while compilation and then using gprof? I am asking this question in order to check if the sampling time of 0.01 second can be lowered further?
