Delays in Synchronization:

When a filtering profile is applied to the source server, there is a slight delay in the time it takes to apply the profile to the target server. This delay is caused by the amount of time it takes the source server to process the change, prepare the update for submission, send the update, and finally to activate the update on the target server. In practice, this should only be matter of seconds. In essence, filtering profiles are shared in near real time with this factor being the only delay.

The delay in activating a library change can take a little longer than in activating a filtering profile change. This is due to the fact that the library on the Web Filter is loaded into the physical memory. When a change is made to the library, a new library must be loaded into memory with the changes. So the delay between the library change taking place is the net of the amount of time it takes the source server to prepare the update for submission, and then the amount of time it takes for the update to be sent, received, and processed by the target server. Once processed, the new library is loaded into memory and activated, while the old version of the library is removed from memory. The total time of this process will vary depending upon custom library entries, but the entire procedure should take approximately one minute.
