( #3333=superdoc: print w/ replies, xml ) Need Help??
my benchmark was run on v5.10.0 built for i486-linux-gnu-thread-multi and vec was by far the slowest.

3 differences:

  • I avoided allocating useless arrays for the result
  • Only tested with non-core modules (too lazy to install)
  • LBNL: I tested with random numbers out of 1..1e6 and you took compact intervals!

Obviously vec scales badly the sparser the distribution of values become...

IMO not very surprising.

update

found bug in benchmark, will correct later. vec still among slowest...

update

Thanks to BrowserUk for vividly commenting twice that the benchmark is broken, after I already mentioned that the benchmark is buggy.

Cheers Rolf
