Python Performance Profiling: The Guts And The Glory

Objective

Attendees will learn which Python profiler to use, and how to use it. They'll see how the profiler's output can guide their optimization efforts, and to estimate the possible improvement from any optimization.

Description

Your Python program is too slow, and you need to optimize it. Where do you start? With the right tools, you can optimize your code where it counts. We’ll explore the guts of the Python profiler “Yappi” to understand its features and limitations. We’ll learn how to find the maximum performance wins with minimum effort.

  I can edit this talk for a 30- or 45-minute slot.

  I gave this talk at PyCon Taipei and the audience really appreciated it:
