WCF服務行爲

Question

我有一個自我託管的WCF服務，我在Windows服務中託管。我的綁定設置爲basicHttpBinding。

當我運行該服務時，我運行netsh http show servicestate並且我看到我的服務正在偵聽;但是，我似乎無法正確配置參數。

當在IIS下託管時，它執行速度慢了20％左右，所以我想自行託管。如何配置我自己託管的WCF服務的參數以匹配IIS？我特別關注的參數是超時，最大連接數，超時和最大請求​​數。我試圖把服務行爲;但是，它什麼都不做。我已經在HTTP /參數下的註冊表中添加了MaxConnections，但沒有成功。任何幫助表示讚賞。

下面是當IIS下舉辦的輸出：

下面是輸出的時候，我自託管：

Answer 1

以下是來自Microsoft HTTP.SYS團隊的官方回覆：

「Max Connections」= HttpServerConnectionsProperty輸出的含義與「Max Requests」= HttpServerQueueLengthProperty的含義不同。

HttpListener不允許爲URL組設置最大連接屬性（HttpServerConnectionsProperty）或請求隊列的最大請求屬性（HttpServerQueueLengthProperty），因此當通過代碼進行自託管時，WCF不能設置http.sys設置。
