RE: Ethernet speed
On a standard developer board with 2.4.19 and with
CONFIG_ETRAX_SERIAL_FAST_DMA_FLUSH (or similar) disabled
you should reach approx 4 MByte/sec for receive and
3 MByte/sec for transmit. With custom hardware you can
reach 5 MByte/sec for receive and 4 for transmit.
To check your application you can do a network trace
(with e.g. ethereal) and check that full size packets
are used. Small packets will decrease the performace.

Subject: Ethernet speed
We are trying to send pictures out of the etrax 100lx. The ethernet physical
chip is configured to
send at 100Mbit. But we cannot achive this speed. We get between 10Mbit and
If we configure the ethernet physical to 10Mbit we get less
Has anyone done performance measuring on etrax's ethernet? What's possible
and how can I speed up my application.
