are there any default perf test in pinot repo that I can use to measure the performance ? I am starting pinot-server with

-XX:ActiveProcessorCount

java opts, so that I can override number of available processors, and workaround the need to request high number of CPUs in k8 deployment. Wanted to do some perf test to reach optimal value.

/**
   * Use at most 10 or half of the processors threads for each query. If there are less than 2 processors, use 1 thread.
   * <p>NOTE: Runtime.getRuntime().availableProcessors() may return value < 2 in container based environment, e.g.
   *          Kubernetes.
   */
  public static final int MAX_NUM_THREADS_PER_QUERY =
      Math.max(1, Math.min(10, Runtime.getRuntime().availableProcessors() / 2));
