I only tried to optimize the first 14 days so far, and to my surprise I have a few times that are slightly better than yours, with an AMD Ryzen 5 3600. My solutions (WIP) are here.

Building and running your code here, I get incorrect results for Day 11. For example, on my input the correct (accepted) answers are 2275, 2121 but my build of your repo says 1228,1132. I don't think the output for your input is correct either. Do you get the correct answers on your computer?
