Beyond OTP
summary
Shows concrete changes to Ranch/Cowboy: replace gen_server-heavy paths with special processes started via proc_lib, remove unnecessary monitoring/try catch and extra message hops, and collapse the acceptor+tracker into a custom supervisor. Measurement claims about effectiveness include 10% throughput improvement and latency 12ms→9ms. Code is implemented, integrated with sys for debugging and used in production experiments, and the changes reduce overhead and improve large‑connection behavior.
