Automatically instrumented python profiling.

Usage

env MAGICPROF=cpu.prof python <app.py> # if MAGICPROF not set, profiling is not instrumented.

# other options:
# MAGICPROF_DISABLE_SUBCALLS # set to anything to disable subcalls. see cProfile.Profile.
# MAGICPROF_DISABLE_BUILTINS # set to anything to disable subcalls. see cProfile.Profile.

Use a tool like snakeviz to visualize the profile.

snakeviz cpu.prof
