ASP.NET 控件的回发请求花费了太多时间

Question

我创建了一个 asp.net 网站http://www.oureasymart.com在 localhost 中运行良好。 但是在将其托管给godaddy之后，当单击asp.net控件之类的按钮时，执行其操作需要花费大约1分钟的时间。 这个问题是针对每个asp.net控制的每一页。 我认为后面的代码或单击事件没有问题，因为我尝试了一个简单的 Response.Redirect() 方法来在单击该按钮时移至下一页，但仍然需要相同的时间。 我也尝试在 Jquery Ajax 的帮助下调用相同的方法，它工作正常。 我还启用了跟踪，在该跟踪中我检查了没有事件甚至需要 1 秒。 请查看跟踪信息的代码和屏幕截图，并提出可能的问题。 跟踪信息： https://drive.google.com/file/d/19Cl6wpe_Y20FCzxI9d0bUvj8BdaUdgjR/view?usp=drivesdk

在跟踪信息中，通过搜索产品然后单击产品搜索页面中的页面索引来截取屏幕截图。

Answer 1

我找到了这个原因。 实际上在按钮单击查看 State 有大量数据，因为我使用了中继器控制。 这导致延迟到达服务器的到达请求。 我为转发器禁用了 View State，这解决了问题。
