The benchmark is wrong atm, the compared functions do not yield the same result.

(comp (map inc) (filter even?)) means filtering first, then incrementing.

The opposite for (->> data (map inc) (filter even?) ...

- which is not the same. And of course, it also means that the latter has to increment the double amount of numbers.

EDIT: It was me who was wrong, thanks for the corrections. Pitfall successfully identified :)
