System Guidelines for Mobile Synchronization Usage

These are general guidelines and are an approximation based on in-house performance testing. There is no guarantee that the recommendations stated below will exactly match each particular clients needs. These estimates are based on moderate mobile synchronization usage. Initial mobile synchronization and complete resynchronization of data tend to have very high cpu usage, depending on the amount of data being synchronized.

System performance will seriously be degraded should a large number of initial synchronizations happen simultaneously.

It may be necessary to run the IMailSync application pool with multiple processes should there be a large number of mobile users.

Warning: IMailSync, IAdmin, and IClient should never be run in the same application pool. Also, both IClient and IAdmin do not support multiple processes.
