not just samba writes to either of the data disks from the network via
samba or scp are painfully slow. Reads from the box to the network are
fast. Copying files from one disk to another one the server are fast.
Taking the disks out of the equation entirely: does scp'ing a file to
/dev/null run fast or slow?

The NIC is sharing IRQ 9 with the USB controller, can you select another
IRQ for the NIC in the BIOS? Especially if you can select a non-shared
one?
Darren,
Forgot about the /dev/null idea. interesting result. I scp'd a 10 Mb
file from my gentoo box and it completed fast in a few seconds - speed
3.3 Mb/s. Not great but faster than the other experiences.
I then did the same with a 2.5Gb file and it started off at 3.3 or 3.5
Mb/sec but tailed of continuously until by the time the transfer was 12%
done the transfer speed was down to 50 kb/sec.
Very strange. Something is not happy here. Does this info give you any
clues? I'm more baffled than before!
thanks
Gary
