I am pleased to announce the first release of Core_profiler. It is a
library that helps you profile programs and estimate various
costs. The library comes in three different flavors:

- "disabled" which does nothing, so that one can leave probes in a
  program without performance penalty
- "online" to print live stats
- "offline" to store data on disk for later analysis

There github project has a wiki page to help you get started with the
library:

And Core_profiler is available in opam:

  opam install core_profiler
