注意到事务timeout是建立在DE - Light网关中的，并且没有从网关到应用程序服务器的反向调用。
Here, the addition of a service provider that requires a timeout value of 30 seconds forces the Web server, ESB gateway, and so on, to increase timeout values respectively.
在这里，服务提供程序的添加需要30秒的超时值，强制要求Web服务器、ESB网关等相应地增加超时值。
Factors such as timeout values, thread pool specifications, and the number of client connections can affect the performance of a DE-Light Gateway.
要素(诸如timeout值、线程池规范及客户端连接的数目)可影响DE - Light网关的性能。
