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.pyThis will produce a profile file vmprof_cpuburn.dat.
Now display the profile:
vmprofshow vmprof_cpuburn.datYou will see a (colored) output:
oberstet@thinkpad-t430s:~/scm/vmprof-python$ vmprofshow vmprof_cpuburn.dat
