Regex library benchmark [closed]

Question

Is there an up-to-date benchmark of contemporary regex libraries? I'm interested in re2, pcre with jit, NSRegularExpression, Irregexp, etc.

I found http://lh3lh3.users.sourceforge.net/reb.shtml and Regular expression library benchmarks both of wich are pretty outdated.

Edit:

I found another link: https://github.com/axiak/pyre2#id6 (Chapter "Performance")

Answer 1

Here is a list of benchmarks:

• A comparison of regex engines – Rust Leipzig
• It's just a simple regex benchmark of different programming languages.
• re2r Benchmark
• Regex Engine Matching Speed Benchmark
• C++11
