Must be. It lacks everything, from content, to truth.
Being someone who has actually tried to do 10Gbps routing using Linux, I am well aware of its limitations. You need lots of tuning and the correct hardware to get high packets-per-second rates, and it gets nowhere close to the target 40Mpps. It really is useful only for large packets, or if you need nowhere near line-rate and don't care about DoS attacks with small packets.
One really needs hardware-assisted packet forwarding to do line-speed 10-gigabit routing at all packet sizes. Either that or a routing cluster, at which point TCO goes well above a proper 10Gbit Cisco/Juniper switch-router.
So, the question becomes: are there affordable, non-experimental hardware packet forwarding devices (preferably PCIe) that are compatible with Linux?
