The 3Com 3c905 driver in FreeBSD uses the card in compatibility mode (non- DMA programmed I/O) and is thus the slowest/highest overhead board that we support. The Intel PCI Pro/100B and Pro/100+ are the fastest/lowest overhead boards that we support, followed by the DEC boards. I haven't measured the performance of the new SMC cards, but I doubt that it is any lower overhead than the Intel cards. -DG David Greenman Core-team/Principal Architect, The FreeBSD Project To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
