So you've got one side at 10Mbps...

150KBytes/sec = 1.2Mbps...

I also noticed:

You've set the 10Mbps interface to full-duplex.  What is on the other 
end?  10Mbps devices are typically half-duplex.  If you have a duplex 
mismatch that would certainly slow down the transfers.  Check error 
rates on both sides of that link.
