Python Statistical Profile tool

PSP - Python Statistical Profiler.

This package provides a simple statistical profiler for Python.

The idea is inspired by google-perftools which uses SIGPROF signal to halt the proccess, collect the whole stack infomations at current frame and after all provide results based on statistics.

Basic usage

It's easy to integrate with psp, here is an example :

from psp import profiler
def fun():
    profiler.Start("output_file_name")
    """ your code """
    profiler.Stop()
fun()

In profiler.Start we passed a file name to the function so when we called profiler.Stop the result woull be written with that file name.

Data processing

Since that all data are serialized in JSON format, it is easy to convert them into other representations.

A example script that parse and output the result to DOT format is included in the source code. Some one have been using the result on a website, which is drawed by [D3.js] [1] [1]: http://d3js.org/ "D3 Javascript liberary"
