Re: [mosquitto-dev] Advice needed (long, sorry)

Hi Karl,

hehehehe. As I said before, we achieved neas 20.000 simultaneous TLS connections. But only connections. As far as we started sending some messages over each everything started to go wrong. :-) This the reason to request your help!!

I've no problem on sharing the sysctl configuration we used. I'm not at home but this evening I'll look for it and I will put it here. please do not flame me if it is not good. We were doing some proof tuning here, and there... Also, mosquitto is running on a 3-cores, 8 GB RAM VM.

I'm actually curious to hear about how you configured mosquitto and your
servers to get 20k connections at all.  I couldn't get anywhere near
that, and the people who'd claimed to reach 100k on mosquitto here in
the past have never replied to any requests for further information.
