[Samba] performance problem on bridgehead DC

[MORILLO Jordi]

Hi everybody

All my DC's are now in 4.7 :-)
I also found today my performance problem: Xenserver 7.0 and 7.1 are crappy and I/O bottleneck.....
No problem with Xenserver 6.5 or Proxmox 5 (which is now hosting my Bridgehead DC)
Have a nice week

No, it is the 4.6 that is causing you the issue.  The unindexed search in the DRS replication server is very slow on 4.6 for a large domain and 4.7 fixes that by correctly using whole-DB locking.  Expect the load to drop to almost nothing based on our user reports.
