Dunno re: 100 Mbps links, but we used to run a full internet
routing table with gated / BGP4 on a 486. It's a radix table so
it didn't have any problems with respect to packet rate.
Unfortunately, gated at the time (8 months ago), combined with
possible bugs in the OS, was *NOT* a stable configuration. The
machine would constantly panic, die, loose track of routes, etc...
I would not suggest it.
