New in version 2.2.
This module provides a nicer interface to the _hotshot C module.
Hotshot is a replacement for the existing profile module. As it's
written mostly in C, it should result in a much smaller performance impact
than the existing profile module.
Note:
The hotshot module focuses on minimizing the overhead
while profiling, at the expense of long data post-processing times.
For common usages it is recommended to use cProfile instead.
hotshot is not maintained and might be removed from the
standard library in the future.
Changed in version 2.5:
the results should be more meaningful than in the
past: the timing core contained a critical bug.
Warning:
The hotshot profiler does not yet work well with threads.
It is useful to use an unthreaded script to run the profiler over
the code you're interested in measuring if at all possible.

-
The profiler object. The argument logfile is the name of a log
file to use for logged profile data. The argument lineevents
specifies whether to generate events for every source line, or just on
function call/return. It defaults to
0 (only log function
call/return). The argument linetimings specifies whether to
record timing information. It defaults to 1 (store timing
information).
