Bear in mind that the kernel will most likely be doing store-and-forward,
unless you the NIC driver was compiled to support direct forwarding, so
unless the application you were using buffer-stuffs (i.e. writes a packet
or two ahead of what it's got acks for) this will have a significant
impact on throughput. What was CPU load like? what happens if you do two
transfers at the same time? in the same direction? in opposite directions?
