Hi Ralf,
thanks a lot... Yes my driver is cciss and seems that your suggestion 
solved my problem.

Now i'm using:

      max-buffers      20480;
      max-epoch-size   16384;
      unplug-watermark 20480;

this are the results now:

version: 0.7.21 (api:79/proto:74)
SVN Revision: 2341 build by lmb at dale, 2006-08-10 14:19:54
 0: cs:SyncTarget st:Secondary/Primary ld:Inconsistent
    ns:0 nr:54787856 dw:54787856 dr:0 al:0 bm:6927 lo:2103 pe:2428 
ua:2103 ap:0
        [==================>.] sync'ed: 93.3% (3853/57349)M
        finish: 0:00:49 speed: 79,792 (48,388) K/sec

drbd0: Resync started as SyncTarget (need to sync 58725576 KB [14681394 
bits set]).
drbd0: Resync done (total 1229 sec; paused 0 sec; 47780 K/sec)

Thanks again to all for help.
Bye,
Marcello
