array sample slower than indexing into rand(size-1)

Nice shirleyquirk! I guess I should just use arrays when performance really matters and I know the size compile time. Would you do it like this? import sequtils import random import times const size = 10_000_000 iterations = 100_000_000 type

I am getting even larger difference between sample and rand(size-1) with flto passed to C time taken sample: 1.021981 time taken rand: 0.098158 nim c -r -d=danger --passC:-flto --passC:-ffast-math hue.nim Nim Compiler Version 1.4.4 [MacOSX: amd64]
