Comment (by xkon):

 Thanks for the 2nd gist @azaozz .

 I gave it a bit more time to gather more data + re-tested with the first
 gist as well and no-cache just to see the difference on calls themselves
 as well.

 I've also run tests x2-3 times each one right after the other as a "stress
 test" and depending on what my pc was doing in parallel I've seen my CPU /
 php burning at some points haha. That as well shows on the occasion of a
 `recurse_dirsize` that went up to `t=131` but then droped down to 60.
 Always using [attachment:"46645.2.diff"] .

 Hopefully this can give better info overall.

 Here goes:
