我正在使用WebSphere Portal8.0开发portlet，并且正在测试基于具有完整配置文件的Portal8.0默认主题的新自定义主题。我创建了四个门户网站页面，每个页面都显示一个portlet。浏览器顶部的水平导航菜单是主题提供的自动生成的导航菜单。当我从一个门户页面切换到另一个门户页面时，有相当多的延迟时间，大约5秒后我在Firebug中看到任何响应，然后整个页面空白最多两秒钟，然后最终加载新页面。我只期望浏览器的主体部分显示当前页面的内容，而不是整个页面，包括标题横幅和导航菜单。可能是什么导致了这个？
是否存在导致此问题的特定主题资源或配置文件？它可能是门户网站本身的一个设置，与主题分开吗？我在测试时打开了Firebug控制台，并注意到每次重新加载相同的dojo1.7模块。为什么没有缓存dojo1.7模块？我从Portal管理控制台验证了每个门户页面允许缓存24小时，我还验证了每个portlet本身也启用了24小时缓存。我还验证了Firefox浏览器启用了250MB缓存。
我创建了基于Portal8.0的自定义主题并将其打包到单个WAR文件中。在我的自定义主题中，我定制了theme_en.html，Default.jsp和commonActions.jsp文件。我已经开始尝试慢慢恢复我对每个文件所做的更改，希望我能够发现导致显着延迟的特定自定义，但到目前为止还没有看到它。
我是否在正确的轨道上？延迟可能是由于定制的主题文件？以下是自定义主题文件：

注意：我很早就设置了跟踪字符串＆＃34; com.ibm.wps.resourceaggregator.CombinerDataSource.RemoteDebug = all＆＃34;通过Integrated Solutions Console按照文章：http://www-01.ibm.com/support/knowledgecenter/SSHRKX_8.0.0/dev/csa2t_trble_tracemod.dita导致门户加载未压缩的js和css文件，以帮助配置自定义主题，但为了加载更快的压缩版本，现在已删除跟踪字符串，我看到Firebug控制台中的错误直接与删除此跟踪字符串有关。最初的两个错误是：

这有什么意义吗？如何删除该跟踪字符串会导致这种情况？
