这是一个总体战略问题。我一直在用 sunspot_rails 修改搜索结果页面的加载时间，并且我注意到了一些奇怪的发现。

  1. 有时，如果加载了其他内容，结果加载速度会更快。

  2. 我越能避免连接表，我就越能轻触数据库。

我很好奇我是否还缺少其他一些很棒的主食。这是我正在解析的搜索结果示例，其中包含有关如果我将项目隔离并自行加载项目所花费的平均加载时间的评论。

All things Commented out = Completed in 554ms (View: 487, DB: 16)
All things loaded = Completed in 9093ms (View: 9008, DB: 37)

您可以加快速度的一种方法是预先计算结果

truncate(sanitize(simple_format(result.about_us), :tags => ''), :length => 100).titleize

这样你的视图只是吐出文本/html。您将有一个 before_save 方法将上述内容放入另一个字段。

但这只是一个猜测——看起来你的视图加载得太慢了，所以这可能是原因。
