VMprof Python client

See https://vmprof.readthedocs.org for up to date info

basic usage:

sudo apt-get install python-dev libdwarf-dev libelfg0-dev libunwind8-dev

pip install vmprof

python -m vmprof

vmprofshow

vmprofshow is a command line tool that comes with VMprof which can read profile files generated by VMprof and produce a nicely formatted output.

Here is an example of how to use:

Run a smallish program which burns CPU cycles (with vmprof enabled):

pypy test/cpuburn.py

This will produce a profile file vmprof_cpuburn.dat.

Now display the profile:

vmprofshow vmprof_cpuburn.dat

You will see a (colored) output:
