I just thought it may reduce some latency for drbd ack packages.
obviously not the issue in your setup.

unlikely to make a noticable difference...
this is fine tuning.
I don't know why you don't get more syncer performance.
with a gigabit crossover ethernet you should get about
30 to 60 MB/sec average sync throughput "out of the box".
*without much tweaking*
you are sure that all the hardware is ok?
the GigE really works in 1000 Mbit mode? (--> mii-tool -v ethX)
no other io going on on the same physical disks?
