Akka远程性能问题

Question

我在Akka远程处理中遇到性能问题。我有两个演员Actor1和Actor2。行动者之间发送的消息是从Actor1到Actor2的同步请求和从Actor2到Actor1的响应。以下是我的Actor:的示例代码片段和配置

Actor1.java:

object Actor1 extends App {
val conf = ConfigFactory.load()
val system = ActorSystem("testSystem1", conf.getConfig("remote1"))
val actor = system.actorOf(Props[Actor1].withDispatcher("my-dispatcher"), "actor1")
implicit val timeOut: Timeout = Timeout(10 seconds)
class Actor1 extends Actor {
var value = 0
var actorRef: ActorRef = null
override def preStart(): Unit = {
println(self.path)
}
override def receive: Receive = {
case "register" =>
actorRef = sender()
println("Registering the actor")
val time = System.currentTimeMillis()
(1 to 300000).foreach(value => {
if (value % 10000 == 0) {
println("message count -- " + value + " --- time taken - " + (System.currentTimeMillis() - time))
}
Await.result(actorRef ? value, 10 seconds)
})
val totalTime = System.currentTimeMillis() - time
println("Total Time - " + totalTime)
}
}
}

Actor2.java:

object Actor2 extends App {
val conf = ConfigFactory.load()
val system = ActorSystem("testSystem1", conf.getConfig("remote2"))
val actor = system.actorOf(Props[Actor2].withDispatcher("my-dispatcher"), "actor2")
implicit val timeOut: Timeout = Timeout(10 seconds)
actor ! "send"

class Actor2 extends Actor {
var value = 0
var actorSelection: ActorSelection = context.actorSelection("akka://testSystem1@127.0.0.1:6061/user/actor1")
override def receive: Receive = {
case "send" =>
actorSelection ! "register"
case int: Int => {
sender() ! 1
}
}
}

}

application.conf:

remote1 {
my-dispatcher {
executor = "thread-pool-executor"
type = PinnedDispatcher
}
akka {
actor {
provider = remote
}
remote {
artery {
transport = tcp # See Selecting a transport below
canonical.hostname = "127.0.0.1"
canonical.port = 6061
}
}
}
}
remote2 {
my-dispatcher {
executor = "thread-pool-executor"
type = PinnedDispatcher
}
akka {
actor {
provider = remote
}
remote {
artery {
transport = tcp # See Selecting a transport below
canonical.hostname = "127.0.0.1"
canonical.port = 6062
}
}
}
}

输出：

我在这里做错什么了吗？。有什么改进表现的意见或建议吗？

Answer 1

我看到的代码的主要问题是Await.result((。这是一个阻塞操作，很可能会影响性能。

我建议将结果收集在一个固定的数组/列表中，使用整数作为数组，并在收到预期数量的响应时认为它是完整的。
