Enumerator::Parallel
require 'enumerator-parallel'
[1, 2, 3].par(processes: 3).each { |n| sleep 1; p n }
[1, 2, 3].par(threads: 3).map { |n| sleep 1; p n }
3 times fater! wow wow wow
You need to take care of side-effecting
$global_var = 1
(0..10).par(threads: 3).map { |n| sleep rand; $global_var += 1 }
There are difference ↑ and ↓ :D
$global_var = 1
(0..10).map { |n| sleep rand; $global_var += 1 }
