I use ZCM 11.2.3, MSSQL Server and Windows 2008 R2. 5 Primary servers.
Workstations are Windows 7 64bits and about 3000 devices.

A zac ref operation can take up to 60''..

I know there is number of other factors as network, number of bundle assignment.. but what are your refresh time based on the number of primary server / devices?
Just to compare with other configurations.

Thanks in advance
