Maybe try GitHub - lpgauth/buoy: High-Performance Erlang HTTP 1.1 Client · GitHub … That’s what I usually use when I need performance, but I don’t think I ever make requests with such a high latency.
Note that it doesn’t implement the full http/1.1 spec: GitHub - lpgauth/buoy: High-Performance Erlang HTTP 1.1 Client · GitHub.
But it is the most performant http/1.1 client afaik: GitHub - lpgauth/httpc_bench: Erlang HTTP client benchmarks · GitHub.
