I'm not sure of the exact context here, but buffer size does matter if
you go to extremes. A TCP sending packets with 1 byte of data will
get a total effective bandwidth that's a lot smaller than a TCP
sending 1024 or larger packets. Not so extreme is in the middle,
working with 100 or 200 byte datagrams; generally the slow down is
still perceptible. Dave Feldmeier at MIT did some work a few years ago
verifying experimentally that there is a plateau point where larger
packets don't give you an appreciable speedup, but it tended to be >
1024 bytes.
