【问题描述】：

我有一个相当繁忙的 SSRS 实例，并且重新渲染性能一直下降到我们将回收时间配置设置为 60 作为解决方法的地步，我仍然在一小时内显着降低渲染性能。一旦 60 分钟过去了，性能就会恢复到可接受的水平并再次开始下降。

我已经使用了配置中的内存设置，但似乎没有什么不同。该服务器专用于 SSRS，似乎没有任何内存压力。在这一秒，大约有 32gb 的内存和 28gb 的可用内存，SSRS 使用大约一个 gig。

查看日志我们有很多以下错误

我已经断断续续地研究了一段时间，但我还是一片空白。

【解决方案1】：

尝试开启Report Server HTTP Log。

然后，您可以在跟踪日志中发生错误时与 HTTP 日志中记录的请求进行交叉引用。请注意，跟踪日志中的时间戳使用本地时间，而 HTTP 日志中的时间戳使用 GMT。

我和你有同样的问题，发现不支持的动词是 OPTIONS，看起来它是由 Microsoft Office 应用程序发送的：

11/21/2018 22:04:17 xx.xx.xx.xx 域\用户 xx.xx.xx.xx 20480 ssrsServer OPTIONS /Reports/Pages/ 405 2589 0 1.1 Microsoft Office 协议发现 - - -

我还不能确定如何阻止这个错误。
