Hello!
When I perform initial sync I see different synchronization speed and ETA
on both nodes at the seme time.

On node1:
version: 0.7.17 (api:77/proto:74)
SVN Revision: 2093 build by root at node1, 2006-03-10 15:23:12
 0: cs:SyncSource st:Primary/Secondary ld:Consistent
    ns:158622036 nr:0 dw:7410516 dr:151219265 al:5186 bm:342968 lo:127 pe:324 ua:1929 ap:1
        [=>..................] sync'ed:  5.6% (2522253/2669919)M
        finish: 4:26:02 speed: 161,768 (156,208) K/sec

On node2:
version: 0.7.17 (api:77/proto:74)
SVN Revision: 2093 build by root at node2, 2006-03-08 17:12:38
 0: cs:SyncTarget st:Secondary/Primary ld:Inconsistent
    ns:0 nr:158219728 dw:158219728 dr:0 al:0 bm:342945 lo:9 pe:1810 ua:9 ap:0
        [=>..................] sync'ed:  5.6% (2522623/2669919)M
        finish: 8:45:02 speed: 81,960 (62,452) K/sec

As you see drbd on node1 synchronizes with 161,768 (156,208) K/sec and
on the node2 with 81,960 (62,452) K/sec. Values differs for about two times.
How can it be?

Thanks!
