We have: vx0 <3COM 3C905 Fast Etherlink XL PCI> rev 0 int a irq 5 on pci0:11 Installed on two 2.2.2-RELEASE machines in our office, each of which are plugged into a 100Mbs port on a Dlink 810 EtherSwitch and are experiencing abysmal slowdowns in transfer speeds compared to what it was like when we didn't have the EtherSwitch, and right now, I'm at a lose as to why. If we try to transfer a file from one of the FreeBSD (100Mbs port) to a Sparc20 (10Mbs port) on the same hub, we get around 600+Kbytes/sec. If we try to transfer that *same* file from FreeBSD (100Mbs) to FreeBSD (100Mbs), through the EtherSwitch, we get around 100Kbytes/sec. The Sparc20 is on one 10Mbs segment, and each of the FreeBSD boxes are on their own 100Mbs segment, so they aren't "sharing" a port. On the flip side, going from the Sparc20 (10Mbs) to one of the FreeBSD machines (100Mbs), we are getting around 14kB/s. Checking the back of the computer/card, the card indicates that it is running in 100Mbs mode for both systems, but beyond that, I'm at a loss for where else to look... One thing we're curious about, and I hate to throw this in, but the etherswitch itself has a switch that allows us to switch from full duplex to half duplex on a port by port basis...currently, its set at full duplex... could this possible relate, or has nothing to do with it?
