I'm not very familiar with 3Com cards at all, but IIRC, the 3c509 is an ISA card, no? Try PCI, as the throughput and CPU load are much more reasonable. That said, my favorite card is the Intel Pro/100 (seems to be a very common favorite among FreeBSD users). I've had boxes with 2 Intel cards that could sustain 750-800Kb/s from one side to the other without issue. I've also had *VERY* good performance going from 100bTX-100bTX networks, but don't have any numbers handy. Hell, I even get good performance with RTL8029 cards (cheap ne2k compatible PCI nics). -- Troy Settle Network Analyst Picus Communications 540.633.6327 ** -----Original Message----- ** From: owner-freebsd-questions@FreeBSD.ORG ** [mailto:owner-freebsd-questions@FreeBSD.ORG]On Behalf Of ** Emmanuel Gravel ** Sent: Wednesday, July 05, 2000 11:06 PM ** To: freebsd-questions@freebsd.org ** Subject: Dual-homed machine, performance problems. ** ** ** I have two 3C509b's in my FreeBSD box.
