Please don't fall into the Meraki Marketing trap. The max number of connected device by Meraki is very tight. I have over 100 clients on MX64 w/o any performance issue.
If need to count clients, you need to add the # of
PCs, Laptops, Desk IP Phones, Printers, Switches, APs, and AP Clients altogether.
What matters is your CPU usage during the business hour.
