Thank you for finding that for me!

Perl regexes are hooked into sqlite using a callback mechanism. But filtering row-wise. That's much slower than a native implementation.

I'm not quite clear on what you mean by "native implementation" - would linking in libpcre2 (or another) as a custom function be expected to perform better? Or would I be better off using a different DBMS with built-in REGEXP support such as mySQL?

(It does appear that both mySQL and SQLite REGEXP can't use the index and have to search the data itself.)
