Identifying performance issues in an application under test (AUT). The AUT executes on a system under test (SUT) in a test environment, and uses one or more context parameters of the SUT and/or the test environment. A rule engine identifies performance antipatterns in trace data generated by the AUT when executing a set of test suites, based on a set of performance antipattern definition rules, each performance antipattern associated with one or more context parameters. One or more performance test suites are identified that cause the AUT to use at least one of the one or more context parameters associated with the identified antipatterns. The list of identified performance test suites is ranked, based on respective priority values associated with each identified antipattern.
