network.instantiate, how much traffic?

Does anyone know how much traffic network.instantiate generates? Lets say you have a multiplayer game that has a lot of bullets on the screen.

Would it be worth having a load of bullets pre instantiated, then recycling them through some kind of organising system?

Or is it fine just throwing out 50 network.instantiate every second?

what I would recommend instead is merely passing ‘start’ and ‘stop’ RPC’s for the gun. And then have each client do the instantiating of the individual bullets on their own. The server should really be the only one that actually takes care of damage though.
