The web-server does the right thing if the `Content-Length' header is present in the response value: https://github.com/racket/web-server/blob/547b3fd736684651e94ebd78902633374be6bcae/web-server-lib/web-server/http/response.rkt#L120 When I change the benchmark to take advantage of that, throughput doubles: https://www.techempower.com/benchmarks/#section=test&shareid=ab930604-6b19-4ab4-a2a5-93e674a81804&hw=ph&test=plaintext&a=2 I'll make a PR against the main repo to make sure all of the responses have content lengths. Out of curiosity, I made the app fork through FFI calls: https://www.techempower.com/benchmarks/#section=test&shareid=0197c25f-d544-4357-b3be-a40d4a8760ef&hw=ph&test=plaintext&a=2 This worked although multiple processes wake up when a connection can be accepted and the IO layer doesn't seem to handle `EAGAIN': racket: Connection error: tcp-accept: accept from listener failed racket: system error: Resource temporarily unavailable; errno=11 racket: context...: racket: .../more-scheme.rkt:261:28 racket: /root/.racket/7.7/pkgs/compatibility-lib/mzlib/thread.rkt:75:14: loop : https://gist.github.com/Bogdanp/b7b72ff7845f7f2c51e64bde553128d0#file-fork-app-rkt-L232-L256 -- You received this message because you are subscribed to the Google Groups "Racket Users" group.
