There are too many variables to answer this sort of question, the only way to find out is to test — hardillb, Jul 13 '18 at 06:03

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
