Bpftune uses BPF to auto-tune Linux systems

I’d rather the kernel present a good-enough but extremely stable set of configs. If I’m using a distro like Arch or Gentoo, then sure, maybe run wild (though both of those would probably assume I’m tuning them anyway), but CentOS, Debian, et al.? Stable and boring. If you change something, you’d better know what it is, and why you’re doing it.

These parameters affect things at the hardware level, and in the kernel. There’s “good enough” defaults already, but if you want to take full advantage of your specific hardware, you need to tune it. This is especially important the more different your hardware is from kernel developers’ computers (like 10g nics).
