If you see collisions, terrible tcp performance & good udp performance, you probably have a duplex mismatch. > Is there any better NIC card that works all right in full-duplex under FreeBSD? I'd strongly recommend the Intel EtherExpress Pro 10/100B. If you end up replacing the DEC DE500-BA, would you consider loaning that card to the if_de driver's author? I'd have done this long ago, but all my cards of this type are built into $10k workstations. ------------------------------------------------------------------------------ Andrew Gallatin, Sr Systems Programmer http://www.cs.duke.edu/~gallatin Duke University Email: gallatin@cs.duke.edu Department of Computer Science Phone: (919) 660-6590 To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-net" in the body of the message
