I am noticing very slow network throughput (like 0.24 Mbps) for this computer. I'm gauging this by FTP'ing a 1MB file around between different machines on our local network. The computer has two NIC cards, but I've only set up/activated one card. According to 'ifconfig' the card is using 100baseTX. I checked the router/hub and it is using FAST ethernet for this machine's connection. I've noticed that the times returned by 'traceroute' between my various machines seem the same, so maybe the problem is just with FTP. 'traceroute -P TCP' (FTP uses TCP, right?) always times out so I'm not sure. I don't know what other "benchmarks" to try. Here's some info I hope is pertinent. bash-2.04$ dmesg | grep fxp fxp0: port 0xcc80-0xccbf mem 0xfe100000-0xfe1fffff,0xfe201000-0xfe201fff irq 17 at device 13.0 on pci0 fxp0: Ethernet address 00:d0:b7:84:92:0e fxp1: port 0xcc40-0xcc7f mem 0xfe000000-0xfe0fffff,0xfe200000-0xfe200fff irq 18 at device 14.0 on pci0 fxp1: Ethernet address 00:d0:b7:84:93:1f bash-2.04$ ifconfig fxp0: flags=8843 mtu 1500 inet 167.76.89.57 netmask 0xffffff00 broadcast 167.76.89.255 inet6 fe80::2d0:b7ff:fe84:920d%fxp0 prefixlen 64 scopeid 0x1 ether 00:d0:b7:84:92:0d media: autoselect (100baseTX) status: active supported media: autoselect 100baseTX 100baseTX 10baseT/UTP 10baseT/UTP fxp1: flags=8802 mtu 1500 ether 00:d0:b7:84:8b:e4 media: autoselect status: no carrier supported media: autoselect 100baseTX 100baseTX 10baseT/UTP 10baseT/UTP lp0: flags=8810 mtu 1500 ppp0: flags=8010 mtu 1500 faith0: flags=8000 mtu 1500 gif0: flags=8010 mtu 1280 gif1: flags=8010 mtu 1280 gif2: flags=8010 mtu 1280 gif3: flags=8010 mtu 1280 lo0: flags=8049 mtu 16384 inet6 fe80::1%lo0 prefixlen 64 scopeid 0xa inet6 ::1 prefixlen 128 inet 127.0.0.1 netmask 0xff000000 I'm not sure where else to look.
