Aaron: 30%?
Matz: 30% is huge.
Aaron: Yeah!
Jonan: That seems like a pretty good improvement to me.
Koichi: I do think so.
Aaron: We just need a few more 30% improvements then Ruby 3x3 is done.
Matz: Yeah, that means 30% of the time is spent in the compiler.
EDIT: maybe they were joking once again?
