synchronization - Disruptor，同步机制

Question

当有 N 个生产者和 1 个消费者时，破坏者队列是否提供卓越的性能？我使用 Disruptor Queues 编写了一个包含多个生产者和单个消费者的程序。我发现结果与阻塞 arraybounded 队列并驾齐驱。后者表现更好。我在这里做错了吗？

public void asynchronous_execution( )
{
 // Set up the executor and disruptor
     ExecutorService exec = Executors.newCachedThreadPool();
     Disruptor<valueEvent> disruptor =
     new Disruptor<valueEvent>( valueEvent.EVENT_FACTORY,
                        globalVariables.RING_SIZE,       
                        exec );

 // Handler of Events
 final EventHandler<valueEvent> handler = new EventHandler<valueEvent>()
 {
     public void onEvent(final valueEvent event, final long sequence, 
                 final boolean endOfBatch) throws Exception
     {  .... }       

 };

 // Building Dependency Graph
 disruptor.handleEventsWith(handler);

 // Starting the disruptor
 final RingBuffer<valueEvent> ringBuffer = disruptor.start();


 // Producer Thread
 final long[] runtime = new long [globalVariables.NUMBER_OF_THREADS];

 final class ProducerThread extends Thread {
  ...

    public void run()
    {
      ..
          long sequence = ringBuffer.next();
          valueEvent event = ringBuffer.get(sequence);

          event.setValue(globalVariables.WRITE_CODE); 

          // make the event available to EventProcessors
          ringBuffer.publish(sequence);  

        ...
       }

       ...
 };


 ProducerThread[] threads = new ProducerThread[globalVariables.NUMBER_OF_THREADS];
 for (int i = 0; i < globalVariables.NUMBER_OF_THREADS; i++) {
    threads[i] = new ProducerThread( i );
    threads[i].start();
 }

 ....

}
