I've tested now the default params with your Queue, but nothing changed:

On same time startet with clusterssh:


root at dhcp1 ~ # dd if=/dev/zero of=/dev/sda bs=1M count=2048
2048+0 records in
2048+0 records out
2147483648 bytes (2.1 GB) copied, 33.3878 s, 64.3 MB/s


root at dhcp2:~# dd if=/dev/zero of=/dev/sdb bs=1M count=2048
2048+0 Datensätze ein
2048+0 Datensätze aus
2147483648 Bytes (2,1 GB) kopiert, 48,319 s, 44,4 MB/s


but, I did a plain network test again (iperf) and i got 111MB/s so, the
network is the problem. :-/
