With an efficient FIB algorithm, a single core on a Xeon 5400 will exceed 30 million lookups per second for IPv4 -- full table and lots of peers. Of course, that fails to accomodate RIB maintenance and FIB updates. It also doesn't take into account modern SMP CPUs; the RIB-handling code is still under development.
