客户端调用wcf服务，如何提升调用性能

IO调用服务

一、使用using(每次自动释放)

  for (var i = 0; i < 10; i++)
                {
                    var watch = new Stopwatch();
                    watch.Start();
                    using (var client = new StreamServiceClient())
                    {
                        var result = client.Upload(new StreamRequest
                        {
                            Bytes = data,
                            FileExt = ext,
                            Passport = ""
                        });
                        if (!string.IsNullOrEmpty(result.Msg))
                            MessageBox.Show(result.Msg);
                    }
                    watch.Stop();
                    this.richTextBox1.AppendText(string.Format("第{0}次：耗时：{1}\r\n\r\n", i, watch.ElapsedMilliseconds));
                }

二、重用wcf通讯通道

for (var i = 0; i < 10; i++)
                {
                    var watch = new Stopwatch();
                    watch.Start();
                    var client = new StreamServiceClient();
                    {
                        var result = client.Upload(new StreamRequest
                        {
                            Bytes = data,
                            FileExt = ext,
                            Passport = ""
                        });
                        if (!string.IsNullOrEmpty(result.Msg))
                            MessageBox.Show(result.Msg);
                    }
                    watch.Stop();
                    this.richTextBox1.AppendText(string.Format("第{0}次：耗时：{1}\r\n\r\n", i, watch.ElapsedMilliseconds));
                }

三、自定义wcf通道

先建立一个channel,以下：

/// <summary>
    /// IO服务通道
    /// by:jgl
    /// date:15-10-10
    /// </summary>
    public sealed class EmpIOChannelFacotry
    {
        private static readonly object LockObject = new object();
        private static StreamServiceClient client;

        public static StreamServiceClient Channel
        {
            get
            {
                lock (LockObject)
                {
                    var locaClient = client;
                    if (locaClient != null && locaClient.State != CommunicationState.Faulted) return locaClient;
                    client = new StreamServiceClient();
                    return client;
                }
            }
            set
            {
                lock (LockObject)
                {
                    if (client == null) return;
                    if (client.State != CommunicationState.Opened)
                        client.Abort();
                    client.Close();
                    client = value;
                }
            }
        }
    }

此文章属于我的记录，我是wcf的菜鸟，但愿你们多多批评与指点。

请问各位还有其余办法可以提供wcf客户端调用的办法吗？
