Installing Win '98 on the same hardware gets me a pretty good transmission rate. >> FTP transmissions happen in small bursts at very regular intervals - >> about 3/4 sec apart > > Check your MTU, are there collisions? No visible collisions, the MTU is 1500 - FreeBSD's default. I haven't overridden this. >> Any clues as to what could be causing this? > > Bad wire? > > WHat brand is it? Good suggestion - I tried a different wire, but no dice - I still get the same problem. Thing is, if I launch an xterm or open a telnet session, typing is still perfectly responsive through the slow transfer, and 'top' says the CPU's staying 90%+ idle, so I really suspect a configuration issue, though I haven't the foggiest where to look. The card is a D-Link 10Mbps Combo 16-Bit Ethernet ISA The box is: 486/66 DEC Server (chuckle) EISA bus 24 megs RAM Adaptec 1540(?) VLB (ahc0) Diamond Stealth 64 Video VRAM VLB D-Link 10Mbps ISA (PnP off - locked at 0x280/9) PS/2 Bus Mouse & kbd Again, this happens with a 10 or a 100/10 Linksys hub, and the other two machines speak to each other (or to this box running another OS) right against the 10mbit barrier.
