Logging 由于控制台日志，Struts 2页面速度变慢

通过在struts.xml中放置以下常量，我禁用了struts 2的开发模式：

<constant name="struts.devMode" value="false" />

但是，我的页面加载速度非常慢，在控制台上可以看到很多mime类型的输出：

 <mime-mapping>
 <extension>pptm</extension>
 <mime-type>application/vnd.ms-  powerpoint.presentation.macroenabled.12</mime-type>
</mime-mapping>
