C# WCF服务运行速度非常慢，具有可靠的会话

服务器托管在WPF应用程序上，并对双工通道使用net.tcp绑定。我们让客户端（.NET 4.0）向服务器发送一个突发异步请求。开启可靠会话后，服务速度会变得非常慢（约50-100次呼叫/秒），回调消息不会发送到客户端

这个问题发生在两种情况下

我们每秒向服务器发送大约1000条消息。如果我们发送300-500条信息就可以了

我们向服务器发送一条大小为10-20MB的消息。在这种情况下，来自服务器回调的消息将等待大消息发送

下面是服务器和客户端的代码

服务器绑定：

BaseTimeout = 7000;
        int.MaxValue = 2147483647;
        ///Common
                CloseTimeout = new TimeSpan(0, 0, BaseTimeout),
                OpenTimeout = new TimeSpan(0, 0, BaseTimeout),
                ReceiveTimeout = new TimeSpan(0, 0, BaseTimeout*4),
               SendTimeout = new TimeSpan(0, 0, BaseTimeout),
                ///Security
                Security = { Mode = SecurityMode.None },
                ///Session
                ReliableSession =
                {
                    Enabled = true,
                    InactivityTimeout = new TimeSpan(1, 10, 0),
                    Ordered = true
                },
                ///Buffer and message
                MaxBufferPoolSize = int.MaxValue,
                MaxBufferSize = int.MaxValue,
                MaxReceivedMessageSize = int.MaxValue,
                ///ReaderQuotas
                ReaderQuotas =
                {
                    MaxBytesPerRead = int.MaxValue,
                    MaxDepth = int.MaxValue,
                    MaxNameTableCharCount = int.MaxValue,
                    MaxStringContentLength = int.MaxValue,
                    MaxArrayLength = int.MaxValue
                },
                //Other
                PortSharingEnabled = true,
                MaxConnections = 1000,
                TransactionFlow = true,
                TransferMode = TransferMode.Buffered,

（我们还尝试使用standart net.tcp绑定自定义的istead，但没有帮助）

客户端配置：

BaseTimeout = 7000;
        int.MaxValue = 2147483647;
        ///Common
                CloseTimeout = new TimeSpan(0, 0, BaseTimeout),
                OpenTimeout = new TimeSpan(0, 0, BaseTimeout),
                ReceiveTimeout = new TimeSpan(0, 0, BaseTimeout*4),
               SendTimeout = new TimeSpan(0, 0, BaseTimeout),
                ///Security
                Security = { Mode = SecurityMode.None },
                ///Session
                ReliableSession =
                {
                    Enabled = true,
                    InactivityTimeout = new TimeSpan(1, 10, 0),
                    Ordered = true
                },
                ///Buffer and message
                MaxBufferPoolSize = int.MaxValue,
                MaxBufferSize = int.MaxValue,
                MaxReceivedMessageSize = int.MaxValue,
                ///ReaderQuotas
                ReaderQuotas =
                {
                    MaxBytesPerRead = int.MaxValue,
                    MaxDepth = int.MaxValue,
                    MaxNameTableCharCount = int.MaxValue,
                    MaxStringContentLength = int.MaxValue,
                    MaxArrayLength = int.MaxValue
                },
                //Other
                PortSharingEnabled = true,
                MaxConnections = 1000,
                TransactionFlow = true,
                TransferMode = TransferMode.Buffered,
