Slow network throughput

I am using the onboard NIC on ASUS A7N8X-X which has NFORCE2 chipset.
But when I transfer data thru LAN from another computer the speed is only 3MB/s. I tested it with a 700MB file with KDEs KONQUERER and also GNOMEs NAUTILUS.
DMA is enabled on the HDD and also buffered read test from HDPARM shows ~60MB/s. So the HDD is definetly not the problem. I am using the NATIVE NFORCE2 drivers

root@pegasus:~# hdparm -tT /dev/hda

 Timing cached reads:   1728 MB in  2.00 seconds = 863.27 MB/sec
 Timing buffered disk reads:  172 MB in  3.00 seconds =  57.30 MB/sec
tom@pegasus:~$ lspci |grep Ethernet
0000:00:04.0 Ethernet controller: nVidia Corporation nForce2 Ethernet Controller (rev a1)
tom@pegasus:~$ sudo ethtool eth0
Settings for eth0:
        Supported ports: [ MII ]
        Supported link modes:   10baseT/Half 10baseT/Full
                                100baseT/Half 100baseT/Full
        Supports auto-negotiation: Yes
        Advertised link modes:  10baseT/Half 10baseT/Full
                                100baseT/Half 100baseT/Full
        Advertised auto-negotiation: Yes
        Speed: 100Mb/s
        Duplex: Full
        Port: MII
        PHYAD: 1
        Transceiver: externel
        Auto-negotiation: on
        Supports Wake-on: g
        Wake-on: d
        Link detected: yes
ps. If I boot into WinXP the throghput is ~9MB/s
