Actually Raku is faster to compile than Perl5. If you consider all of the features it comes with.
For example, in Raku everything is an object with meta features. If you add Moose or similar to Perl5 then the compile times will often take longer than the equivalent Raku times. That's not the only such feature that you have to add to Perl5 to get feature parity. Then you have to also realize that the Perl5 compiler has had since 1994 to get faster vs. 2015 for Raku.
