What the file says
# SQL Server Wait Statistics Review Skill ## Purpose Analyze SQL Server wait statistics and identify the dominant bottleneck using the **Waits and Queues** methodology. Applies 44 checks (V1–V44): V1–V18 classify each significant wait type into its root cause and produce a prioritized remediation plan; V19–V26 perform multi-snapshot trend analysis when 3+ time windows are provided — detecting worsening trends, spikes, peak periods, and emerging bottlenecks; V27–V29 cover specialized scenarios (PAGELATCH on user databases, backup I/O, cumulative skew from outlier events); V30–V36 cover modern feature wait types (In-Memory OLTP, Columnstore, Query Store, Transaction/DTC, Service Broker, Full Text Search, Parallel Redo); V37–V40 add DMV-level memory and I/O detail — forced memory grants, grant timeouts, stolen memory, and file-level I/O latency (requires optional capture queries); V41–V44 cover SQL 2019/2022 IQP/PSP/ADR feature-specific wait types and TempDB memory-optimized metadata contention (SQL 2019+). …
