Question

我使用struts2创建了一个web应用程序，使用mysql创建了hibernate。我迁移到播放框架，所以现在我有两个应用程序实例，其中一个用struts2编写。我可以看到游戏的性能大幅提升，但是当我使用JMeter来模拟加载时，struts2版本的缩放比使用更低的延迟更好。为什么这样，这是否意味着坚持使用struts2更好？ webapp（我从localhost测试，两个应用程序都有相同的代码，除了模板语言，struts2在tomcat7上运行，而在独立服务器上运行时运行）

您需要根据应用程序的配置文件配置线程模型。更具体地说，您的应用程documentation建议采用以下配置：

play {
  akka {
    event-handlers = ["akka.event.slf4j.Slf4jEventHandler"]
    loglevel = WARNING
    actor {
      default-dispatcher = {
        fork-join-executor {
          parallelism-min = 300
          parallelism-max = 300
        }
      }
    }
  }
}

Play Framework高延迟
