Umbraco 7 在生产服务器上运行缓慢并不断重启

Question

umbraco 项目在我的本地笔记本电脑上运行完美，但是当我将它放在生产服务器上时，后端非常慢。

VPS规格：

Windows 服务器 2012
1 CPU 2 核 2.2Ghz
4Gb 内存
IIS8
MSSQL Express

Umbraco 版本

7.4.1

此外，当我在后端添加新节点或其他更改时，它有时会挂起，然后我在日志中看到应用程序已重新启动。

日志见下：

有人对此有什么建议吗？

Answer 1

我最近遇到了同样的问题并关闭了检查索引，因为它强制更改了配置。

尝试一下，转到 /config/ExamineSettings.config

并注释掉供应商

<providers>
  <!--
  <add name="InternalIndexer" type="UmbracoExamine.UmbracoContentIndexer, UmbracoExamine"
       supportUnpublished="true"
       supportProtected="true"
       analyzer="Lucene.Net.Analysis.WhitespaceAnalyzer, Lucene.Net"/>

  <add name="InternalMemberIndexer" type="UmbracoExamine.UmbracoMemberIndexer, UmbracoExamine"
       supportUnpublished="true"
       supportProtected="true"
       analyzer="Lucene.Net.Analysis.Standard.StandardAnalyzer, Lucene.Net"/>

    <add name="ExternalIndexer" type="UmbracoExamine.UmbracoContentIndexer, UmbracoExamine"/>
  -->
</providers>

它应该会在每次保存内容时停止重新启动应用程序池，但我不知道为什么 Indexer 会强制刷新
