Native pure-perl6 Text::CSV is faster than Text::CSV_XS in combination with Inline::Perl5. The performance of Inline::Perl5 must be abysmal then. What's the performance of Perl6 (FOR GAWD'S SAKE AT LEAST DROP THE SPACE FROM THE NAME OF THE OTHER LANGUAGE!) Text::CSV compared with Perl Text::CSV (not CSV_XS)? Jenda Enoch was right! Enjoy the last years of Rome.	[reply]

Today it is (time in seconds needed to parse 10_000 lines of CSV with 5 fields each): `Perl5 0.016 Text::CSV::Easy_XS 0.016 Text::CSV::Easy_PP 0.033 Text::CSV_XS using bind_columns () 0.037 Text::CSV_XS 0.504 Text::CSV_PP (Text::CSV) 1.295 Pegex::CSV Perl6 17.474 Inline::Perl5 + Text::CSV_XS line-based 17.057 Inline::Perl5 + Text::CSV_XS IO-based 18.182 Inline::Perl5 + Text::CSV_PP (perl5's Text::CSV) 13.577 Text::CSV (perl6's Text::CSV) 49.948 CSV::Parser` [download] There are plans to work on optimizing NativeCall soonish, so all timings using Inline::Perl5 might speed up because of that. The timings for Text::CSV::Easy_?? are timing the use of a module that only parses 100% valid CSV. It offers no options to deal with abnormalities. Given these numbers, we (the perl6 community) still need an overall performance gain of a factor 27 (13.6 → 0.5) to be able to say that pure-perl modules in perl6 are as fast as comparable pure-perl modules in perl5. Personally I don't envision perl6 becoming as fast as perl5 with dedicated XS code, as Text::CSV_XS, at least not in the foreseeable future. Enjoy, Have FUN! H.Merijn	[reply] [d/l]

So the quickest solution in Perl6 is only about 367 times slower than the "default" Perl5 solution. I guess I'd wait for a few more Christmases even if I actually liked the language. Jenda Enoch was right! Enjoy the last years of Rome.	[reply]

I am not CSV user, but - if anyone says me that Inline::C does not give you enough performance - then there is something wrong with implementation. How come some XS module utilizes Inline::C?? When you're using XS - you already at C level. What a design requires you to use Inline::C Therefore your sentence about performance is not convincing, and even - other way round - I now suspect there's something hidden in calculation here.

This includes at least four levels of indirection, none of which includes perl5 module Inline::C	[reply]

ok, /me wrong: it was Inline::Perl, ok then...	[reply]
