Working on this problem for months now and I can't find the problem. I also used the FreeBSD as a NATd server for my ADSL(tun0) connection.
I have some other server demons running, but switching them off gives no positive effect on the upload speed (average it's 10 times slower than down).
When I disconnect the Internet the problem isn't solved, so it's not a lookup loop. Problem is not solved by setting all NIC's to 10 or half duplex.
This problem accurse with NFS, Samba and FTP so it's not a configuration of these demons.
Please replace the Reltek card, because a realtek chip-set based NIC will over preform on a FreeBSD box, courses connection losses and wrong media detections.
However I have exactly the same problem using a 3Com for my LAN connection:
# ifconfig xl0 xl0: flags=8843<UP‚BROADCAST‚RUNNING‚SIMPLEX‚MULTICAST> mtu 1500 options=3<RXCSUM‚TXCSUM> inet 192.168.0.1 netmask 0xffffff00 broadcast 192.168.0.255 ether 00:04:75:98:d6:bd media: Ethernet 100baseTX <full-duplex> status: active
Have tested my HDD speed but this is good (12MB/Sec read and 9MB/Sec write, random).
This is generated with tcpdump during a heavy upload (500MB), I don't have a clue what it means but maybe somebody can have a look at this.
# tcpdump xl0

More information about the system is found on Http://info.zaleo.homeunix.net (PhpSysInfo)
As you can see a lot of "err" on this device only when I upload to the FreeBSD-Box, strangely there are no collisions on the network and I have also tried a direct twisted pair connection.
If you need more specific information please let me know, we are really desperate to solve this performance problem.

This has gotta be a software issue... it seems logically impossible for it to be otherwise. I have my windows box running off a nat on my fbsd box, it transmits to my isp at a max of about 160k down 70k up. Transfering files between the two boxes can be done at a max of 1.6M down and 130k up. Hense its physcially impossible for it to be a hardware problem. This is all quite annoying as both boxes are connected by http://www.startech.com/ststore/itemdetail.cfm?tab=b&ProductID=ST100S&topbar=topbara.htm 10/100 nics and a 50' crossover cable. Anyone have any ideas on what is causing this issue and how it could possibly be resolved?
Here is the output from ifconfig on the bsd box: rl0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500 inet 192.168.0.1 netmask 0xffffff00 broadcast 192.168.0.255 inet6 fe80::250:fcff:fe71:a11b%rl0 prefixlen 64 scopeid 0x1 ether 00:50:fc:71:a1:1b media: Ethernet 100baseTX <full-duplex> status: active rl1: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500 inet6 fe80::250:bfff:fe17:63a2%rl1 prefixlen 64 scopeid 0x2 inet 142.59.160.131 netmask 0xfffff800 broadcast 142.59.167.255 ether 00:50:bf:17:63:a2 media: Ethernet autoselect (10baseT/UTP) status: active lp0: flags=8810<POINTOPOINT,SIMPLEX,MULTICAST> mtu 1500 lo0: flags=8049<UP,LOOPBACK,RUNNING,MULTICAST> mtu 16384 inet6 ::1 prefixlen 128 inet6 fe80::1%lo0 prefixlen 64 scopeid 0x4 inet 127.0.0.1 netmask 0xff000000 ppp0: flags=8010<POINTOPOINT,MULTICAST> mtu 1500 sl0: flags=c010<POINTOPOINT,LINK2,MULTICAST> mtu 552 faith0: flags=8002<BROADCAST,MULTICAST> mtu 1500
