我有一个托管在 Windows 服务中的自托管 WCF 服务。我的绑定设置为 basicHttpBinding。

当我运行服务时，我运行 netsh http show servicestate 并且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，它的执行速度会慢 20%，所以我想自己托管。如何配置我的自托管 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、超时和最大请求​​数。我试图提出服务行为；但是，它什么也没做。我在 HTTP/Parameters 下的注册表中添加了 MaxConnections 也没有运气。任何帮助表示赞赏。

以下是在 IIS 下托管时的输出：

以下是 Microsoft HTTP.SYS 团队的官方回应：

“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 在通过代码自托管时无法设置 http.sys 设置。
