Brad, I second your claim of high capacity Linux routers. (my comments are not specific to MT) Our newest generation of Linux Routers are easilly passing 4-5Gbps through it.
The secret to fast Linux routers was several fold. The first was to get to a 2.6 kernel, and NAPI support on drivers. The other was to get quad core processors, if multiple Bus slots were used. The reason being bus slot tends to assign itself under the control of adifferent Processor core. With straight traffic passing, they really fly. The weak link though is teh limited Intel clock.Many badnwdith management techniques time around the clock limited to 100 ticks per second. This can majorly limit bandwdith management routines that run on the routers. (For example typical HTB setting ideal for 1-5 mbps speeds, start having problem once 10mbps is reached. Customization is needed to handle the higher speeds. It can handle the badnwdith management of the higher speeds (100mbps to end user) well also, but then as a side effect it has problems with lower speed circuits. In otherwords it gets hard to have the same router than manages 100mbps circuits to also manage 1-2mbps well. Anyway, I'm sure many of these things can be solved by smarter bandwidth mangement configurations. However, for some routers applciations, to get full capacity of the router (our cores), we opted to bypass any bandwdith management, and use it like a switch, and only do Bandwdith Management on the cell routers closest to the csutomer. But it can really be sweat using Linux fo BGP routers, expecially if you plan to process alow of BGP session/tables for BGP to the custoemr. I do not have secific experienmce with exactly what MT can do, but I'm sure its near equivellent on similar hardware platforms.
