I’ve been running multiple “ab” instances, but it’s concurrency understudying is weird. you can’t have number of requests be lower than concurrency - so with ~100k connections, it was doing about 1m of requests, and it was load bandwidth up to 1.5Gbit. So after that I wrote small python app (with genets) which is doing many connections, and doing only 1 request - so now number of connections and requests about the same, bandwidth ~500-600Mbit > Anyway, please bump maxconn (both global and default), just to make sure > you don't hit a limit there.
