我正在使用.NET 3.5和WCF开发服务器-客户端应用程序。绑定= BasicHttp。
我正在Windows 2003 Server SP2中工作和部署该服务。

服务器中的服务由控制台应用程序自行托管,而在我的计算机中,一切正常。事实是,当我将服务器部署到计算机中时,它应该运行,打开serviceHost实例大约需要15秒钟,而这应该是毫秒。我可以忍受,但是当此实例从客户端接收到第一个请求时,它需要花费恰好15秒的时间来响应,并且对于每个新客户端来说都是这样。在第一个请求之后,只需几毫秒即可响应以下内容。

我的计算机没有这个问题,我已经尝试了许多其他方法,并且工作正常。我无法格式化要在其中部署的服务器,因此我需要一些有关该特定计算机或配置中可能存在问题的建议。
对于要在该计算机上托管的任何服务,甚至是“ WCF服务库”模板中的基本示例,都将重复这种行为,因此,为简单起见,我在解决此问题的同时对其进行了处理。
这是我在主机应用程序中使用的app.config。其余代码正是上述模板之一。
请记住,该服务运行良好,是导致该服务无法使用的延迟。

提前致谢 !

最佳答案

我将从在客户端使用小提琴手开始,看看发生了什么。如果有非HTTP较低级别的网络问题,如果需要,您也可以进行netmon。

在服务器端,您可以分析,跟踪或记录以查看在15秒钟的请求期间,服务器代码花费了多少时间。

这些至少会告诉您从哪里开始。

如果是针对每个客户端的新请求,则应查看身份验证,DNS名称解析和其他网络配置。另一个好的实验是在请求用户15秒后,回收服务器应用并再次发出请求。再过15秒?如果不是,则可能是网络,如果是,则是app / config中的某些内容。
