My theory is wasteful protocols. (If such terminology even exists)

I have similar observation. Mine maxed out at 12MB as well, though the
speed dropped to 7MB after I converted from single drive on the media
server to Raid6. (Local read/write speeds are now higher, yet transfers
over the network are slower)

I don't trust interwebs speed tests.
