Hi all

I installed drbd 0.7.12 and checked, if the sync speed is better as before, 
because it synced with approx. 50mb/s over a GBit link. I think, it should 
be hundreds of  mb/s. So i hoped, 0.7.12 would solve this problem, at least 
increase the sync speed a little. But the opposite happend. Now i have a 
sync speed under a mb/s, as you see below.

Im running Fedora Core 4 with 2.6.11-1.1369_FC4smp kernel. The mirror net 
device (eth1) has a mtu of 9000, which was recommended by Alan Robertson in 
case of sync speed problems.

Any idea?
