YAPC day 2: something, something

[ #6014 ]

Someone else is giving gnat's something, something talk. MJD stayed for this talk, so I figure this'll be good.

Something, something faster is a condensed version of a three hour optimization talk. With a lot of cussing. Our cussing was surprisingly provided by a Disney employee standing in for gnat. I haven't trusted Disney for family entertainment in years, so I wasn't nearly as surprised as some people.

Management is optimizing the users away.

There's some profiling stuff here. That's good; I like profiling.

There's a Benchmark.pm module that will run something repeatedly and see how long it takes. In 5.8 it will take its own overhead into account.

Devel::SmallProf runs for each line, which makes it slow.

csh has a better version of the time command, but that's still not an excuse for using csh. :)

Function calls are ~25% faster than method calls. If Perl 6 fixed only that about the OO model, it would be great.

I've finally had the Schwarzian transform explained to me! Now I understand. map sort map.
