Re^2: Rakudo Perl 6 and MoarVM Performance Advances

FWIW, perl6 -ne 'say ~$0 if m/(<<\w**5>>)/' … is much faster. Something likely needs to be optimized in Match.gist. It's still much slower than Perl 5

Additionally, appending `for lines` gives a significant gain over using `-n`, so that needs works as well. EDIT: I agree that '-n' should be what is used here, I was moreso posting in the interest of figuring out why that's so slow. I just made a PR which seems to bring the time for '-n' to be more like that of 'for lines'	[reply] [d/l] [select]

It could be argued you're then comparing different things. The original is strictly a comparison of the equivlaent Perl one-liners.	[reply]

They are not quite equivalent. `say $0` actually dumps the whole match tree of that capture (something that doesn't even exist in Perl 5), it just happens to be a single string in this case. Still the code that is behind it is must consider the general case. It shouldn't make such a big difference, though. Perl 6 - the future is here, just unevenly distributed	[reply] [d/l]
