Low bandwidth

Hi, guys !
I have a small network at home and I noticed something curious... When I 
try to copy from one computer to another (the transfer is made through 
the server - without a switch), the bandwidth is very low, about 2Mb/s. 
Does anyone know why ? Another thing is that the bandwidth from the 
server or from one of the "home" computers to the "outside" LAN is very 
low too, about 700Kb/s up to 1.5Mb/s. Does anyone know why is that ?
Here is what ifconfig shows me :

-------------------------------------  [ifconfig]

xl0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
        options=8<VLAN_MTU>
        inet 172.17.53.39 netmask 0xffff0000 broadcast 172.17.255.255
        inet 195.225.67.97 netmask 0xfffffff0 broadcast 195.225.67.111
        ether 00:10:4b:24:5f:f0
        media: Ethernet autoselect (100baseTX <full-duplex>)
        status: active
fxp0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
        options=8<VLAN_MTU>
        inet 192.168.0.1 netmask 0xffffff00 broadcast 192.168.0.255
        ether 00:d0:b7:0b:57:e4
        media: Ethernet autoselect (none)
        status: no carrier
fxp1: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
        options=8<VLAN_MTU>
        inet 192.168.1.1 netmask 0xffffff00 broadcast 192.168.1.255
        ether 00:d0:b7:2b:9e:9d
        media: Ethernet autoselect (100baseTX <full-duplex>)
        status: active
plip0: flags=108810<POINTOPOINT,SIMPLEX,MULTICAST> mtu 1500
lo0: flags=8049<UP,LOOPBACK,RUNNING,MULTICAST> mtu 16384
        inet 127.0.0.1 netmask 0xff000000

-------------------------------------

An the machine info...

-------------------------------------  [uname -a]

FreeBSD sergiu-it.tarnita.net 5.3-RELEASE FreeBSD 5.3-RELEASE #1: Mon 
Apr  4 19:08:47 EEST 2005     
root at sergiu-it.tarnita.net:/usr/src/sys/i386/compile/server i386

------------------------------------- 

xl0 is the NIC connected to the "outside world", fxp0 and fxp1 are 
connected to two computers that I have in separate rooms at home. I 
don't know if it's important, but I use ipfw and natd to give access to 
"home" computers to the "outise world".
So, if anybody have any ideea... I'd like to hear it ;-)
Thanks !
