I constantly get between 154 and 156 ns/url when running on an M2 Air 2022 while using asahi linux instead of MacOs.
22 Celsius according to smartmontools :)
So seems a good part of the speed-up comes from using the Linux kernel, which tbh. doesn't really surprise me.
It's hard to match the engineering amount and quality getting poured into it (well at least the core stuff, some niche driver will be a mess like everywhere).
The remainder then comes from modern x86_64/amd64 CPU combined with DDR5 beating the M2, well at least in this micro benchmark.
