Question

对于拥有大型网站的客户，我们一直在大量投资2sxc。我们已经构建了许多自定义应用，并在默认的内容应用中添加了不少内容类型。

大约一个月前，我们开始看到在保存前端数据和在Content App中保存ContentTypes时速度缓慢（但仅限于此）。该网站需要20 - 30秒才能保存。现在它变得更糟，并开始间歇性地抛出异常。保存不会超过30秒。在其他时间它是60秒。间歇性内容无法保存，我们收到下面列出的错误消息和例外。

但是，我们在其他应用中保存内容没有任何问题，例如Blog应用和我们的自定义应用。表现很好。此外，2sxc模块通常似乎对前端用户来说很好。

我们在DNN 7.4.2上运行2sxc 8.4.5。

这是最初的错误消息：

DNN事件日志中出现两个例外。对于每次保存失败，它们都会出现两次。

感谢RaphaelMüller，这个问题已经解决了。他建议在数据库上重建索引。完成后，内容保存从45秒加上超时到1.5秒。男孩是我的脸红。哦，生活和学习。教训很简单：确保您的数据库有一个包含重建索引的维护计划。

以下是可能遇到此问题的人的一些有用链接。

这是一个重建数据库中所有索引的脚本。理论上，脚本不应该锁定您的数据库或网站，但任何事情都是可能的，因此最好在非工作时间执行。在我的DNN数据库上运行大约需要5分钟，大约2.5 Gb。 https://gallery.technet.microsoft.com/scriptcenter/Script-for-rebuilding-all-8d079754

Michelle Ufford的索引碎片整理脚本是一种高级解决方案。我已成功在我的舞台服务器上运行它，它似乎受到社区的欢迎。 http://sqlfool.com/2011/06/index-defrag-script-v4-1/

以下是有关计划索引重建的频率的有用讨论。 How Often should the indexes be re-build in sql-server DB?
