LN 客户端通过 netTCPBinding 的 WCF 服务超时，美国客户端工作正常

Question

我有一个通过 TCP 绑定公开的 WCF 服务，在纽约的服务器上运行。连接到该服务并从美洲连接到该服务的客户获取结果时没有任何问题，但来自伦敦/欧洲的客户却遇到了问题。我不太确定为什么会发生此超时问题，但以下是客户端和服务器设置。

服务器

<system.serviceModel>

                    maxArrayLength="2147483647"

我的客户端在 C# 代码中具有以下设置

private DataServiceClient GetClient(string uri, int? timeout)
    {
        EndpointAddress endpointAddress = new EndpointAddress(new Uri(uri),
                                                              EndpointIdentity.CreateDnsIdentity("localhost"),
                                                              new System.ServiceModel.Channels.AddressHeaderCollection());
        NetTcpBinding svcBinding = new NetTcpBinding();
        svcBinding.Security.Mode = SecurityMode.Message;
        svcBinding.Security.Message.ClientCredentialType = MessageCredentialType.Windows;

        svcBinding.MaxReceivedMessageSize = 2147483647;
        svcBinding.MaxBufferPoolSize = 2147483647;
        svcBinding.MaxBufferSize = 2147483647;
        svcBinding.MaxConnections = 10;

        svcBinding.ReaderQuotas.MaxBytesPerRead = 2147483647;
        svcBinding.ReaderQuotas.MaxDepth = 2147483647;
        svcBinding.ReaderQuotas.MaxArrayLength = 2147483647;
        svcBinding.ReaderQuotas.MaxNameTableCharCount = 2147483647;
        svcBinding.ReaderQuotas.MaxStringContentLength = 2147483647;
        if (timeout.HasValue)
            svcBinding.SendTimeout = svcBinding.ReceiveTimeout = new TimeSpan(0, timeout.Value, 0);
        else
            svcBinding.SendTimeout = svcBinding.ReceiveTimeout = new TimeSpan(0, 5, 0); // this is default

        PIERDataServiceClient dsc = new PIERDataServiceClient(svcBinding, endpointAddress); //this is wcf client from ClientBase
        return dsc;
    }

有 WCF 超时问题经验的人可以解释一下吗？我一直在尝试关注各种论坛上的无数帖子，但我收集的理解以及以代码和配置形式实现的内容并没有多大帮助。

TIA， 什拉万
