How many clients can the Qg 2 handle?

The number of clients handled in unicast is defined by the product name. E.g. Qg 2, 32 slaves handles 32 clients independent on the message rate. If both ports of the Qg 2 are acting as unicast master, the product name gives the total number of clients over both ports.  In multicast, the number of slaves handled is defined by wire speed, at 1 Gb/s this theoretically means ~100000 slaves at 1 delay request/sec.
