The speed for upload and download can be measured with, for example, pages like: http://www.speedtest.net/ the results vary of course a bit, but usually they are between 1 and 4 Mbps; how those values fit with the speed of the device /dev/cuaU0.0 which I set in ppp.conf to the maximum value as set speed 921600 and as well in /usr/include/sys/_termios.h I don't see any higher possible speed for the interface... do I miss something?
