Question

我有一个自托管的WCF服务，我在Windows服务中托管。我的绑定设置为basicHttpBinding。

当我运行该服务时，我运行netsh http show servicestate，我看到我的服务正在监听;但是，我似乎无法正确配置参数。

在IIS下托管时，它的执行速度大约低20％，因此我想自我托管。如何配置自托管WCF服务的参数以匹配IIS？我特别关注的参数是超时，最大连接数，超时数和最大请求数。我试图提出服务行为;但是，它没有做任何事情。我在HTTP /参数下添加了MaxConnections，但没有运气。任何帮助表示赞赏。

以下是在IIS下托管的输出：

这是我的服务配置文件：

Answer 1

以下是Microsoft HTTP.SYS团队的官方回复：

“Max Connections”= HttpServerConnectionsProperty输出与“Max Requests”= HttpServerQueueLengthProperty的含义不同。

HttpListener不允许您为URL组设置Max Connections属性（HttpServerConnectionsProperty）或为请求队列设置Max requests属性（HttpServerQueueLengthProperty），因此WCF无法在通过代码进行自托管时设置http.sys设置。
