So far I have found why nginx-clojure is slower than http-kit when 10000
concurrents. (when < = 1000 concurrents nginx-clojure is faster than
http-kit.)
I have set too many connections per nginx worker (worker_connections =
20000) . This make nginx only use one worker to handle ab requests (every
request is tiny).
I plan to take note of
c-erlang-java-performance<http://timyang.net/programming/c-erlang-java-performance/>and
fork
clojure-web-server-benchmarks<https://github.com/ptaoussanis/clojure-web-server-benchmarks>to
do some real world tests.
