How many users support Mikrotik rb3011.
I make just load balancing with vlans connecting to cisco switch.

The number of users you can support is usually more related to the network traffic they make, which is often limited by the internet speed that you have, than by the actual number of users.
The load that the network traffic imposes on the router depends on the firewall rules, the usage of fasttrack, etc.
