I'm most interested in the g_ether driver at the moment, so I ran a a little test piping 5GB of video data down and back up with netcat, host$ nc -l -p 5011 | pipebench -b4096 | md5sum lpd7a404# nc -l -p 5010 | nc 192.168.4.1 5011 host$ (while true; do cat video.nuv ; done) | dd bs=1000 count=5M | \ | nc -q 1 192.168.4.2 5010 Summary: Piped 4.88 GB in 03h03m16.62s: 465.59 kB/second 62db86e45d0dce4627fe604cfdc379b5 - The md5sum is correct. 465KB/s is half the overall throughput since its a round trip, so total bandwidth would be ~930KB/s, which I think is pretty good for a 12Mbit link, allowing for TCP and URB overhead. The old lh7a40x_udc driver could not sustain this kind of throughput, and the TCP connections would typically stall after < 100MB. Thumbs up on the new driver! -Jamie ------------------------------------------------------- This SF.Net email is sponsored by xPML, a groundbreaking scripting language that extends applications into web and mobile media.
