Why is the transfer rate non-linear with respect to the system clock? At 100 MHz the rate is 1.38 Mbit/s and at 200 Mhz it is 65.4 Mbit/s.

Latency kills...and Ethernet uses exponential backoff.

[crote]

More specifically TCP uses exponential backoff. Ethernet will happily keep drowning you in packages at line rate, if I'm not mistaken.

[daymanstep]

CSMA/CD does use exponential back off, though I'm not sure if anyone is still using it.

This is only for half-duplex ethernet communication so no one apart from some archaic systems.

Like WiFi?

[edward28]

CSMA/CA but close.

[pantalaimon]

There is also 10Base-T1 which is a rather recent addition.

It's a physical layer, so yeah, of course it will.

[vardump]

Maybe a lot of CRC errors or something. Just a guess.

[rscott2049]

Wish I could answer that! All I can guess is that the slower processing speed creates a bottleneck in the LWIP stack somewhere...
