I want to buy a vps with the following specifications:
and a dedicated server
How many connected clients does each server support with vernemq or mosquitto with QOS 1?
Well, I have solved the doubt, for more than 1000 users you just have to modify the file /etc/init.d/mosquitto
add the following line to the beginning of the file
ulimit -n 20000
where 20000 is the number of connections to support
