Start with the linked benchmark source in src/benchmarks/micro/libraries/System.Collections/PriorityQueue/Perf_PriorityQueue.cs and run the provided benchmarks_ci.py command. Compare the Dequeue_And_Enqueue result with the linked baseline and test reports; the issue does not define a code change or a clear completion condition, so triage must establish what action is needed.
