The thing with these minimalist benchmarks is that they aren't comparing a real workload, or a real server/client pair that can leverage persistent connections (the SYN/ACK rounds in setting up a TCP connection have a lot of impact on this kind of thing), internal async/threading mechanisms in the server (different language runtimes and different threading models make a lot of difference as well), and $DIVINITY knows what other kinds of request parsing variations. It's a fun exercise (I do it myself on occasion), but requires understanding what is actually happening (I see that Jarred has already remarked that Bun.serve() would be the right thing to do here, for instance.)
