That’s the filesize benchmark actually, which does IO. The “reference” baseline is 2.10ms.
So it’s really 0.08ms vs 1.00ms overhead difference. ~10x slower! Which is shout in line with the “deep” state difference (268us vs 2.40ms).
And heftia’s difference between shallow and deep is notable. Vs effectful which has barely any difference.
So for a boring web app without tight SLAs..who cares those are peanuts..but if I’m managing a 16ms frame time budget in my game, I wouldn’t bother with heftia and stick to effectful (or cleff which is similar).
