Scala 为什么我在阿克卡派演员的人数减少了？

我有一个由100名正在运行的演员组成的演员池，他们共享一个窃取工作的调度器，其CorePoolSize设置为100。但是现在，当向其中一个参与者发送19条消息时，19条消息没有与19个参与者并行，只有5条消息并行运行。当这5条消息完成后，接下来的5条消息将再次由这5个参与者处理，以此类推。为什么我的19条信息没有并行运行，我在这里遗漏了什么

我的代码基本上如下所示：

object TestActor {
  val dispatcher = Dispatchers.newExecutorBasedEventDrivenWorkStealingDispatcher("pool")
                   .setCorePoolSize(100)
                   .setMaxPoolSize(100)
                   .build
}

class TestActor(val name: Integer) extends Actor {
    self.lifeCycle = Permanent
    self.dispatcher = TestActor.dispatcher
    def receive = {
       case num: Integer => {  println("Actor: " + name + " Received: " + num)
                               Thread.sleep(10000)
                            }
    }
}

trait CyclicLoadBalancing extends LoadBalancer { this: Actor =>
    val testActors: List[ActorRef]
    val seq = new CyclicIterator[ActorRef](testActors)
}

trait TestActorManager extends Actor {
     self.lifeCycle = Permanent
     self.faultHandler = OneForOneStrategy(List(classOf[Exception]), 5, 5000)
     val testActors: List[ActorRef]
     override def preStart = testActors foreach { self.startLink(_) }
     override def postStop = self.shutdownLinkedActors()
}

val supervisor = actorOf(new TestActorManager with CyclicLoadBalancing {
val testActors = (1 until 100 toList) map (i => actorOf(new TestActor(i)))   
}).start

println("Number of Actors: " +  Actor.registry.actorsFor(classOf[TestActor]).length)

val testActor = Actor.registry.actorsFor(classOf[TestActor]).head

(1 until 20 toList) foreach { testActor ! _ }

输出：

Actor: 4 Received: 16
Actor: 3 Received: 17
Actor: 1 Received: 19
Actor: 59 Received: 1
Actor: 2 Received: 18

// 10 secs. are passing..

Actor: 4 Received: 15
Actor: 3 Received: 14
Actor: 1 Received: 13
Actor: 59 Received: 2
Actor: 2 Received: 12

// 10 secs. are passing..

Actor: 4 Received: 11
Actor: 3 Received: 10
Actor: 59 Received: 3
Actor: 2 Received: 8
Actor: 1 Received: 9

// 10 secs. are passing..

Actor: 4 Received: 7
Actor: 3 Received: 6
Actor: 59 Received: 4
Actor: 2 Received: 5

编辑：我使用的是Akka 1.0，我认为dispatcher允许您自定义吞吐量属性。这定义了调度器应在一次扫描中处理的特定参与者的消息数。您可以在akka.conf文件中添加以下配置

actor {
  throughput = 20
}

---

默认值为5

感谢您的询问，我将瓶颈定位并在提交给Akka master的过程中修复了它：

它将在Akka 1.1-RC1中发布

干杯，

你用多少条线来支持它？我在哪里可以找到？我基本上使用的是这个config.file：我试图修改核心池大小因子配置，但没有改变任何东西。但我认为这是为默认调度程序准备的。……您好，谢谢，我会检查一下：）还感谢在Akka上所做的伟大工作，到目前为止，我对框架非常满意：）
