Use the SQL Performance Analyzer report to compare a SQL tuning set from a workload replay to another SQL tuning set from a workload capture, or two SQL tuning sets from two workload replays.
Comparing SQL tuning sets with Database Replay provides more information than SQL Performance Analyzer test-execute because it considers and shows all execution plans for each SQL statement, while SQL Performance Analyzer test-execute generates only one execution plan per SQL statement for each SQL trial.
