Q: 6
Anna has been testing a model and is concerned about the time certain actions seem to be taking.
Her development environment is a high-end system, and other portlets she has developed have not exhibited the kind of response time lag that she and her testers perceive. She suspects one of the data services builders is experiencing network latency, but is unsure where the real problem lies. What actions can she take to help isolate the performance issue?
A. System tracing is enabled by default. Anna can check SystemTrace.log for model action times.
B. Consult the performance log, which is created by default with each model run.
C. Enable system tracing in the run configuration tab to log the execution time for each action (page or method).
D. Dedicate a larger Java HEAP_SIZE to the main method associated with the model that is suspect.
