Runtime standard deviation report provides the following information.
Packages running slower or faster than configured standard deviation limit.
Performance history graph for last N executions.
Average Execution Time
Standard Deviation of Execution Time
Extracted and loaded row count
How many executions per package:
Performance Drop Limit (Default= +1): If you don't want to detect performance drop then set this to 0 (zero). Setting higher limit will detect packages with smaller performance drops.
Performance Increase Limit (Default= -1): If you don't want to detect performance increase then set this to 0 (zero). Setting higher -ve limit will detect packages with smaller performance increase. Abnormal performance increase can be due to many reasons (e.g. Less records loaded than expected, files not found etc.)
