But it's clear that Perl 6 is going to get a lot faster in 2013.

... based on microbenchmarks of a language that isn't Perl 6?

No. You've picked up on what I consider a point of interest rather than the big picture.

The outlook for Perl 6 speed improvement in 2013 is based on many factors:

• I mentioned several factors in my post. For example, Larry Wall declaring speed to be the #1 blocker of adoption in November.

• There are other factors I didn't mention. For example, Rakudo is sufficiently complete that the existing core hackers are fairly free to focus on other things, and speed is increasingly becoming a priority for Jonathan and Moritz. Furthermore, as Moritz notes, the Rakudo toolchain has reached the point that non-core-hackers are successfully hacking on AST generation and NQP to improve speed (with the nice side effect of leading them toward being new core hackers). I could continue but I recommend anyone interested visits #perl6 and asks questions.

As for "a language that isn't Perl 6" I'll point out that NQP is basically a small subset of Perl 6 (NQP stands for Not Quite Perl) and Rakudo compiles to NQP. So if NQP gets faster, Rakudo Perl 6 gets faster.
