Hi guys, I've written up a longish blog post about my recent experiments with Nim performance tuning for numerical calculations. I guess this is pretty basic stuff for people who do C/C++/assembly programming on a daily basis, but I actually learned a lot while doing this exercise and encountered some really surprising behaviour. So I think the article might be useful for other people less experienced with low-level programming too.
