The default sync period is 60 minutes (that is, the minimum time interval that must pass between synchronizations for a project). The precise time does depend on the amount of synchronized projects and synchronization jobs.

**This is separate from the discovery check that ALI/ALM performs to determine if any projects require synchronization (the default value for this is 10 minutes).

So, for example:

- Your project was synchronized at 8:00.
- You make changes to your project at 8:15.
- The scheduler runs a discovery check at 8:30. Result: Synchronization is NOT performed for your project.
- Your project is going to be synchronized at 9:00 IF there is a free synchronization job available.

There are three Site Configuration parameters you can manipulate for configuring the ALI Scheduler (as of ALI version 2.0.0.128336 or later).

**Be aware that improper scheduling can cause performance issues on your server, so take care when changing the default values.

**ALI_MAX_PROJECT_SYNC_JOB** - The maximum number of synchronization jobs that may run at the same time (default value = 5).

**ALI_PROJECT_SYNC_DISCOVERY_INTERVAL** - The interval between checks to determine if any project requires synchronization (default value = 10 minutes).

**ALI_MIN_PROJECT_SYNC_PERIOD** - The minimum time interval that must pass between synchronizations for a project; the precise time depends on amount of synchronized projects and synchronization jobs (default value = 60 minutes).
