Routine monitoring can uncover gradual degradation in performance that indicates the need for more processing power or physical RAM, depending on the bottleneck discovered. With a very large SAM database, this time increases as the system pages in the entire account database. Time to create a new local or global group increases as the total SAM size grows very large. For example, as the total SAM size increases above 60 MB, adding users to a group that already contains 20 percent of the total user accounts takes longer as more users are added to the group. Replication of large SAM databases is also a consideration with respect to network bandwidth usage.
Domains use incremental synchronization for replicating updates.
Adding more users, computer accounts, and groups adds a variable amount of network traffic depending on the frequency of password changes and group membership change operations.
