C# Wcf并行和异步调用？

我有一个wcf服务（解析器服务，字节[]=>string）

托管在iis上（nettcpbinding） 在我的客户端，我有一百万字节以上的[]，类似于这个列表（1000000），我应该调用wcf服务的方法来并行解析这个列表

我是这样使用的，但是在500000-700000消息解析之后，我遇到了一个瓶颈（wcf服务没有响应我）。我在哪里犯了错误？如果我实现这个方法，它能解决我的问题吗

我的wcf主机配置：

我建议您使用PerCall InstanceContextMode，在这种模式下，它为不同的调用创建不同的实例，并在不同的线程中调用它们；如果您使用PerSession，它只为您的会话创建一个实例，根据您的客户端代码，它只创建实例并为您的请求提供服务。

在PerCall情况下；我是否需要从Service1客户端并行创建新实例。Foreach循环？挂起服务需要多少时间（大约）？它会在5分钟以上睡眠，同时不响应数据检查，并查看是否给您提供线索
