I getting used to atop - nice tool to have a summary of what's going on.

it showed that cmds ate 50% of the cpu power.

i've started the MDS on another computer. with 3 osds (1 disk per osd) 
and journal on a partition (same disk as osd) i get now 47 mb/s in dbench 
10 test (ceph data/metadata size 1) and with "size 2" 31.3649mb/s

dd bs=1M count=8192 gives me 107mb/s ("size 1")

so now ceph outperforms samba. :)
