I did some more quick testing. The bottleneck seems to be the context-switching of Linux. When increasing the amount of data sent per sendto() call to 11k I got 41Mbit, and with 22k I got 46Mbit. If bandwidth is very important, maybe you should consider using an 80MHz 860P instead of the 860T. //Marcus -- Signature under construction, please come back later. ** Sent via the linuxppc-embedded mail list.
