Since H. Merijn Brandt started working on the Perl 6 version of Text::CSV, he has kept a log of how long a specific test (referred to as test-t) too to run. https://tux.nl/Talks/CSV6/speed.log https://tux.nl/Talks/CSV6/speed.log Since then, Rakudo Perl 6 has become more than 100x as fast, at least for this test. And more than 250x as fast using a concurrent version of the test (which was as simple as putting a `.race` in the code). This makes it still slower than the Perl 5 version, which uses XS (all parsing logic written in C). But the gap is closing with another round of optimizations to be merged later this week after an extensive refactor that took about 2 months. Of which you will most certainly see a report on https://6guts.wordpress.com https://6guts.wordpress.com , the blog of Jonathan Worthington.
