re2 2.27.0: concurrent matching without the GVL

by Paul Mucur —

A new version of the Ruby bindings to RE2, a “fast, safe, thread-friendly alternative to backtracking regular expression engines like those used in PCRE, Perl, and Python” is now out and releases the Ruby Global VM Lock when performing matches.

This gives a near-linear speed-up when using the gem in a multi-threaded environment (e.g. with Puma) and there’s a toy benchmark in the release notes to demonstrate.
