So I could inject in keep-alive at 100 concurrent threads but it was very slow (2200 req/s at 12% CPU), idling on I-don't-know-what. And at 1000 threads (still 100 concurrent connections), it immediately ate all my memory and got killed by the OOM killer : Out of memory: Kill process 7134 (filed) score 779 or sacrifice child Killed process 7134 (filed) total-vm:7680976kB, anon-rss:7140908kB, file-rss:1988kB, shmem-rss:100kB oom_reaper: reaped process 7134 (filed), now anon-rss:7143588kB, file-rss:1980kB, shmem-rss:100kB 7 GB for 100 connections is a bit excessive in my opinion :-) There are definitely still a number of issues to be addressed before it can be used in production, you definitely need to have a more robust architecture and request parser first.
