Maybe I should buy more of those > cheap rl cards. The fxp driver needs about 12% less system CPU than the de driver, that is significant. A different matter is that the de driver seems to need a little less interrupt time (which does more damage than system time), but the difference is little and could be benchmarking sloopyness. How could you come to the conclusion the rl is as good as the de. Read my mail again, rl under FreeBSD is suicide.
