some statics and pipes, there is actually a whole perl bowl of spaghetti
generating that … the testbed starts for like 5 minutes, eats 25G of
memory, opens 30k passive BGP connections and is able to serve and
consume about half a gigabit of BGP stream on something over 30 threads

there is quite some fiddling with that and virtually no documentation to
the performance testbed, and also probably some crude hacks have never
left the testbed machines

but i still feel impressed by the sheer flow of valid BGP which is
BIRD 3 able to serve, whenever i run any perf test
