Hi ElMaestro,

❝ I get about a 10% speedup difference if I unroll 4x:

Confirmed.

❝ 10% isn't bad, actually. One could probably even optimise the number of unrolls.

Yeah, but at the end of the day it’s not necessarily the loop-overhead that counts. Such a code is terrible to maintain.

PS: In your unrolled code set runs <- 5 and after execution type length(v2). Kinetica-style.
