max gigabit speed


between ckci and badbox2
test: NetCPS
jumbo 9K frames
50K writes/reads to/from socket
direct connection: 79.6 MBs
through switch: 78.0 MBs
CPU utilization: 10..15%

1024 x 768 x 3 x 25 = 58.9 MBs
1024 x 768 x 3 x 30 = 70.7 MBs

Looks like uncompressed XGA over Ethernet is doable, for sure at 25 FPS and maybe at 30.
Whorld to FFRend? FFRend to FFRend? Problem is they both use 4-byte pixels, not 3.

1024 x 768 x 4 x 25 = 78.6 MBs    <- not quite! USB3 instead?
