BigInt is really really slow when run on linux, Or just Boehm GC issue?

Have to mention, another post.

Build with --release performance is slow than the 2017 crystal version?

I am reading a old blog post, which write by @lbarasti , on Apr, 2017, more than five years old! in original post, he build one CPU intensive script for benchmark, use ruby, Crystal, Crystal with --release and NodeJs. Following is those code link: ruby/crystal version js version code paste here too. # loop.cr size = 10 ** 5 a = (1..size).map{ [rand(1000), rand(1000)] } def dist(u,v) (u[0] - v[0]).abs + (u[1] - v[1]).abs end a.each_with_index {|u,i| print "\r#{i}" if i % 100 == 0…

Though, after do some Array/Tuple and puts trick, the performance is better, but, i think, we have to investigate why those code even unchanged, can gain that kind of performance in 2017, if we use those trick that time, still will beat Crystal 1.4 a lot?

BTW: above code run more than 18 mins … still no result. 8X slow than before.
