Nothing scientific about them. I did a few trials FTPing a 600MB file around on a 100Mb switched network between to machines (they were not identical, but used the same ones for both tests), once with Intel PRO/100 adapters, and once with 3com parralel tasking (forgot the model number) adapters. I watched top both times, and noticed that the Intels had lower interupt %s, and finished the job about 5-30 seconds faster (varied on each run). Both machines used wu-ftpd and were running FreeBSD 3.2 - R at the time. > > fxp0: The Intel driver is by far the highest preformance model, > > beats the 3com (second best) hands down with much lower CPU > > overhead. > > Do you actually have any numbers to quantify this?
