Disk Scheduling and Management

Indicates that the log scans are running faster than the network sends. This is an issue only if network sends are slower than expected. This wait is for internal data structures and is usually is very short with no direct effect on data access.

For example, for a task that runs every 10 seconds, after one execution, Always On Availability Groups waits about 10 seconds to reschedule the task, and the wait is included here. Used for the spinlock that grants access to it.In computing, scheduling is the method by which work specified by some means is assigned to resources that complete the work.
