+# SQL Performance Analyzer
+
+SQL Performance Analyzer (aka SPA) as part of Real Application Testing focuses on detailed statement analysis of a defined SQL workload made available via a SQL Tuning Set (STS). The workload runs twice - once BEFORE the change and then AFTER a change. The resulting reports are a detailed comparative analysis (before and after the change) of the individual statements, measured by different metrics such as elapsed time, cpu_time, etc. Optionally, you can automate the tuning process using SQL Tuning Advisor or SQL Plan Baselines.
