# Fizz Buzz Fast as F*ck

High throughput Fizz Buzz

https://codegolf.stackexchange.com/questions/215216/high-throughput-fizz-buzz

There have been several improvements from the naive implementation.

Namely: 

- manual loop unraveling

- custom buffering for `write(2)` instead of `printf(3)`

This has increased the throughput from 236 MiB/s to 1.04 GiB/s.

In the future, there are a couple of optimizations I envision.

1. Vector operations. Use `#include `?

2. Branchless programming. What kind of performance improvement would this provide?
