Where is the bottleneck?

Have you ever felt like your software is eating your resources and you have no clue why? Have you reviewed all the lines, debugged and printed everything but you still don’t know what’s wrong?

In this talk I will conduct a fast intro of a basic set of tools you can use to diagnose your software’s performance and then we will go through a simple piece of code to show how those tools work and what you can expect from them

This set of tools will include basic ones given by the OS itself like htop, lsof, ps and more advanced ones that let you plot the memory usage for given functions like memory_profiler, check CPU usage and the call graph between functions like cprofile and kcachegrind and others.

By the end of the talk, you should have an idea of which are the most typical causes that can make your program slow and you will have a list of tools to search for and identify the source of the problems.
