Then something is wrong with your hardware implementation or processor initialization. A 50 MHz 850 will easily process the 10 Mbit Ethernet and IP stack with cycles to spare. Ensure you have the caches enabled and all pipeline debug modes disabled. There could also be something wrong with your PHY connection, generating lots of noise/errors that requires IP retransmission, although this really shouldn't cause trouble. -- Dan ** Sent via the linuxppc-dev mail list.
