This might be due to disk-thrashing caused by excessive swapping, or some other IO bottleneck issue server-side. (Once the files hit the network they transfer quickly so networking is not the issue here at all. Also the html pages themselves are received in less-than 300ms further confusing matters, though I note that the html is cached by wp-supercache meaning that for most requests very little PHP code is touched, if any.)
