Checked my setup: Somebody told me a while ago that read ahead isn't of any use for networked setups ... I changed the value from 0 to the original and the speed got up significantly. Now I'm getting the 1000kB/s expected by your description :) But the boot time over the net with the new settings did not increase by a significant factor ...
