Get-DbaSpinLockStatistic View Source Patrick Flynn (@sqllensman) Windows, Linux, macOS Synopsis Retrieves spinlock contention statistics from SQL Server’s internal synchronization mechanisms Description Queries sys.dm_os_spinlock_stats to return detailed statistics about SQL Server’s spinlock usage and contention. Spinlocks are lightweight synchronization primitives that SQL Server uses internally for very brief waits when protecting critical code sections and memory structures. This information helps diagnose severe performance issues caused by spinlock contention, which typically manifests as high CPU usage with poor throughput.
