now back to the task at hand, optimizing the 323. changing the mtu on NIC and 323 to 6000 as that seemed to be the best balance on the servers.

copy from file server to 323
13m @ 13,783,465

copy from 323 to file server
16m @ 11,264,611

weird.. i give up for tonight

as if this wasn't complicated enough, 6k block size now causes video streaming to run like crap. dropping to 3k fixes this, so now re-running with 3k on both ends.

copy from file server to 323
14m @ 13,649,969

interesting side note here is that the traffic flow through the NIC was very consistent at around 12% vs. the huge peaks and valleys seen with the 6k block size.

copy from 323 to file server
18m @ 10,499,374

on this copy, the major peaks and valleys are back again with some interesting troughs at 0%

so, it looks like i need to wait for my new NIC's to arrive before doing any more testing.
