Performance IP F5 WCF绑定大，性能差

当使用带有负载平衡器的NetCpBinding的WCF时，我面临性能不佳的问题

我们有一个win form应用程序，它使用WCF（net.tcp协议）。在生产中，我们有一个web服务器场，它有3台带有负载平衡器（F5）的服务器。托管在IIS中的WCF。我们只使用1个用户进行测试

现在，当我们将WCF指向特定服务器时（使用服务器名称或IP）；应用程序的性能确实很好。然而，当我们给出DNS名称（以便请求通过负载平衡器）时，性能会显著下降。网络团队表示，从那边看，一切正常。请帮忙

以下是我在WCF web.config文件中的配置

真正感谢任何反馈或建议。另外，当WCF与NetTcpBinding一起使用时，F5上的建议设置是什么

我现在可以用了。这是负载平衡配置问题。我们已将虚拟服务器类型从标准更改为性能（第7层）。性能没有提高到可接受的范围
