Faster, Faster! Improving regex performance with atomic grouping, possessive quantifiers and more!

Correction: at 27:20 it was stated that the default cache is 50. It

(Peter Lovett) Greedy, Lazy or Possessive? Improving regex performance with atomic grouping, possessive quantifiers and more!
Regex can be a powerful fuzzy text processing tool. But large data starts to show how regex can be slow. This talk will examine some of the reasons why regex can be slow, and what can be done to improve performance.
Many of the techniques covered are also applicable in other programming tools that use regex.
This is not an introduction to regex talk; an understanding of basic regex, and regex in Python, is assumed.
