I agree. A faster processor or maybe more accelerator hardware might be needed. The FB2900 is the upgraded version of the FB2700 which can route around 350Mbps. I don’t know what the speed of the FB2900’s big brother the FB6000 series is, but that’s horribly expensive at something like £12k [!] and so that’s only for ISPs and corporates, and I don’t think even that is fast enough for 10Gbps flows.
I really wish they would add QoS support into the Bricks. They get away with not having it by having a heuristic which is that small packets have priority, so eg TCP ACKs, VoIP or streaming video packets, and DNS lookups get prioritised.
