A ryzen 2300X has 256KB of instruction cache, that's 4x64 KiB 4-way set associative. How can you hope to fill that? I've personally ran gentoo on a 4.2GHz i3-5

I've personally ran gentoo on a 4.2GHz i3-530 as well as a 4.5GHz FX-4350. From kernel to firefox, I only gained performance going from -O2 to -Ofast. I have no hopes of considerable cache misses on a modern CPU.
