Tuning Active Sync Adapter Performance

Because synchronization is a background task, how you configure an Active Sync adapter can affect server performance.

Use the Resources list to manage Active Sync adapters. Choose an Active Sync adapter and access start, stop, and status refresh control actions from the Synchronization section of the Resource Actions list.

To improve Active Sync adapter performance, do the following:

• Evaluate and adjust polling intervals based on the type of activity being performed.

  The polling interval determines when the Active Sync adapter will start processing new information. For example, if the adapter reads in a large list of users from a database and updates these users in Waveset each time, you could run this process in the early morning every day. Some adapters have a quick search for new items to process and can be set to run every minute.

• Edit the synchronization file for the resource to specify the host where the adapters will run.

  You can configure Active Sync adapters that require more memory and CPU cycles to run on dedicated servers to help load balance the systems.

• If you have the appropriate administrator capability, you can change Active Sync resources to disable, manually start, or automatically start Active Sync adapters.

  When you set an adapter to automatic, the adapter restarts when the application server starts. When you start an adapter, it runs immediately and executes at the specified polling interval. When you stop an adapter, it stops the next time the adapter checks for the stop flag.

• Adjust the level of detail captured by the synchronization logs.

  Synchronization logs capture information about the resource that is currently processing. Each resource has its own log file, path, and log level. The amount of detail captured by the adapter log depends on the specified logging level. You specify these values in the Logging section of the Synchronization Policy for the appropriate user type (Waveset or Service Provider).
