  You wont notice any problems till you get way above 3 Mb/s .. so no
problems I'd imagine. Or your firewall .. I am pleasantly surprised how
well the firewall performs - its also dealing with dns and http and mail
border gateway ...

 The only trick was learning how to write the firewall rules as a file
and then load it in one shot - running iptables command each time is
exponentially slow because each invocation pulls the entire current rule
set- modifies it and puts the entire thing back to kernel space - for
each rule you add! I got 1 - 2 order of magnitude speedup doing this.
Course once you do iptables-save then the cost is loading the single table.
