(Assume the best case)? Yes, it can. I have seen a benchmark which basically said that a single quad core cpu with ~3GHz was enough for about 4 links with 10 *gigabit* each. That said, VPNs can slow down processing dramatically, iptables less so. If you want to saturate links with 10 gigabit, you need to use a special qdisc, which might prevent you to do QoS. > I think, There is calculation to identify the packet processing time in linux kernel (kernel & hw cpu freq). I am not aware of this.
