i'm a newbie to asp.net core i'm write a web api service, which store passed data to database. in theory there is about 300-400 request per second to server in future and response time must be less than 10 seconds
but first of all i try to run some load test with locust. i write simple app with one controller and only one post method which simple return Ok() without any processing.
i try to create load to this service for 1000 users. my service run under ubuntu 16.04 with .net core 2.1 (2 Xeon 8175M with 8 GB of RAM). Locust run from dedicated computer
but i see only ~400 RPS and response time about 1400 ms. For empty action it is very big value. i'm turn off all loging, run in production mode but no luck - still ~400 rps. in system monitor (i use nmon) i see that both cpu loads only for 12-15% (total 24-30%). I have about 3 GB free ram, no network usage (about 200-300 KB/s), no disk usage, so system have hardware resource for handling request. so i think, that there is problem with some configuration or may be with system resource like sockets, handles etc
i also try to use libuv instead of managed socket, but result is same in kestrel configuration i setup explicitly Limit.MaxConnection and MaxUpgradedConnection to null (but it is default value)
so, i have two question: - in theory, can kestrel provide high rps? - if first is true, can you give me some advise for start point (links, articles and so on)
