[back to package description]

hs-speedscope

hs-speedscope is a simple executable for converting an eventlog into a format suitable to load into speedscope.

WARNING: Only GHC 8.10 supports generating an eventlog with the correct events for this program to work.

Usage

  1. Create an eventlog which contains time profiling events by running your program with program +RTS -p -l-au.
  2. Run hs-speedscope on the resulting eventlog hs-speedscope program.eventlog.
  3. Load the resulting program.eventlog.json file into speedscope to visualise the profile.
