the Ruby 2.7 benchmarks [0] seem to shows that Ruby is slightly faster than Python 3, or at least fairly competitive. Though things like Python 3 going from 18

  Ruby version of regex-redux uses built-in regex support, and I'm not even sure if it uses it the most performant way. Significant portion of the Python test case is FFI code to directly link PCRE bypassing even normal Python extension support. I guess I should augment some of the SBCL benchmarks with custom assembly then...

    > …SBCL benchmarks with custom assembly then… How could that possibly effect the performance of the Ruby regex-redux? :-) "Wanted — Ruby PCRE2 regex-redux program" https://salsa.debian.org/benchmarksgame-team/benchmarksgame/-/issues/374 https://salsa.debian.org/benchmarksgame-team/benchmarksgame/...

      It wouldn't help ruby, but I'd rather write common lisp ;)

        Fair enough :-) (Although they wouldn't be accepted — the option of using those widely libraries is only for pi-digits and regex-redux; and not "custom assembly".)

  I've also found that the Computer Language Benchmarks Game benchmarks tend to be less and less representative of real workloads, due to what the benchmarks do and to the philosophy of "write it to make it fast, not idiomatic, and parallelize things that would typically not be parallelized". Just taking a look at the benchmark code makes it clear it's very far from idiomatic Ruby code.

    I think it's unfortunate that you've chosen to make such vague disparaging comments. Here are 37 Ruby programs — https://benchmarksgame-team.pages.debian.net/benchmarksgame/measurements/yarv.html https://benchmarksgame-team.pages.debian.net/benchmarksgame/... Presumbly you can show us 2 lists: which of them are your idea of "idiomatic" and which are not ? Merry Christmas.

  > Python 3 going from 18.45 seconds to 2.67 seconds on the regex-redux You do realize those are different programs, don't you? You do realize that both those Python programs are shown in the current measurements, don't you? https://benchmarksgame-team.pages.debian.net/benchmarksgame/performance/regexredux.html https://benchmarksgame-team.pages.debian.net/benchmarksgame/... But if you really want to show us the old Q6600 measurements so many people have complained about, the latest version is here: https://benchmarksgame-team.pages.debian.net/benchmarksgame/q6600/performance/regexredux.html https://benchmarksgame-team.pages.debian.net/benchmarksgame/...
