There are performance tests of OptaPlanner running weekly against master branch. To make sure no regression goes unnoticed, create and alert that will e.g. send an email when there is a performance drop.

This may be a good task for Drools. It would be also beneficial to provide this feature to other KIE perf tests - Drools and jBPM.

Rules that should be checked (the numbers might change, just for illustration):

• a single regression > 10%
• multiple regressions > 5%
• last 5 results dropped by > 10% in total
