Slow network.

I'm looking for some pointers as to why this is happening.

I have a machine with 2.4.25/2.6.4 (boots over network) that serves 2 hard
disks to my network.

It has a microstar ms-6163 systemboard (I think that's the right number), a
160gb maxtor as hda. hda contains an ext3 filesystem. Nic is a 3c905b with
MBA. 256mb memory. 700mhz (100fsb) pIII.

Reading a 2.9gb file off hda is took 1:51 minutes (~26mb/sec).
When I do this over nfs, it takes over 8 minutes (~5.7mb/sec).

I used to get around 11mb/sec transfer from this machine. The changes I
made was a different board/cpu/memory/kernel version and used an 80wire ide
cable for hda. The nic is the same, hda is the same.

The old machine was a celeron 333a, 40wire ide cable, 192mb ram. I don't
know what the board model was. With the old board, I saw about 32mb/sec on
the same file (local) and 11mb/sec (nfs). The kernel was 2.4.20.

Does anyone have any ideas? I looked at ifconfig, vmstat, /proc/interrupts
but nothing looks out of the ordinary.

I almost want to just downgrade the machine, but i like the microstar board
better (faster cpu).
