5 Steps to Speed Up Your Data-Analysis on a Single Core

Material for my talk at the PyConDE & PyData Berlin 2022

Description

Your data analysis pipeline works. Nice.
Could it be faster? Probably.
Do you need to parallelize? Not yet.

We'll go through optimization steps that boost the performance of your data analysis pipeline on a single core, reducing time & costs. This walkthrough shows tools and strategies to identify and mitigate bottlenecks, and demonstrate them in an example. The 5 steps cover:

• Identifying bottlenecks: Profiling
• Efficient IO
• Vectorization
• Memory & Precision Tradeoffs
• Jit-ting with numba

This talk is suited for data scientists on a beginner and intermediate level, typically working with a numpy/scipy/… stack or similar. The talk gives strategies & concrete suggestions how to speed up an existing analysis pipeline, which is demonstrated practically on an example, showing the gained speed improvements of each step.
