我有一个用于负载测试的客户端应用程序,用作有效负载生成器。该应用程序是IIS中托管的WCF服务的客户端,具有安全的wsHttpBinding。此外,IIS中托管的WCF服务是一个中间层,它也是使用netTcpBinding在Windows服务中托管的另一个异步WCF服务的客户端。
在进行负载测试时,我无法超过每秒10-12个请求。我有正确的限制配置,如下所示。
以下是我在IIS中托管的服务的客户端应用程序的配置

为了提高IIS托管的WCF服务的性能,您可能需要调整应用程序池设置。以下代码段显示了示例配置设置:
<system.web>
<applicationPool maxConcurrentRequestsPerCPU="x" maxConcurrentThreadsPerCPU="x" requestQueueLimit="x"/>
</system.web>
