See <http://www.29west.com/docs/THPM/latency-interrupt-coalescing.html>

Shared memory architectures [in switches] are normally better than
having a fixed buffer per port as not all ports will be used
simultaneously at the edge. A 25 MB shared memory buffer for gigabit
speeds corresponds to roughly 200 ms, which is reasonable.
