Gruntjs 为什么CSS grunt任务在30毫秒内完成，但页面需要7秒才能重新加载？

我正在使用grunt查看我的html和css文件，并在它们更改时重新加载浏览器。如果我对html进行更改，页面几乎会立即重新加载，但是如果我对某些CSS进行更改，我会在命令提示符下得到以下打印结果

Execution Time (2015-03-10 16:02:07 UTC)
loading tasks                                        5ms  █████████ 17%
newer:copy:styles                                   10ms  █████████████████ 33%
copy:styles                                          8ms  ██████████████ 27%
newer-postrun:copy:style...ules\grunt-newer\.cache   6ms  ██████████ 20%
Total 30ms

尽管它说它在30毫秒内完成了所有与CSS相关的任务，但页面重新加载新的CSS几乎需要7秒钟

有人能解释为什么会这样吗？作为记录，我没有使用SASS或更少，只是使用普通CSS。如果需要，我可以链接我的Gruntfile.js

编辑：这是我的命令提示符在css更改时给我的完整详细输出

我无法找到此问题的适当解决方案，但是，如果您在“监视”任务下的GrunFile中添加以下内容，则可以缩短一些响应时间：

  options: {
    spawn: false
  }

这不是严格意义上的CSS问题，特别是grunt问题。@Jack删除了CSS标签。你是如何测量7秒来加载CSS的？@Matthew Well首先，我只是做了更改并开始计数，但在cmd中还显示“总计30毫秒”之后，"6年完成。725s@AzzyDude您是否可以将输出（包括已显示的咕噜时间输出）发布到它表示完成时间的位置？提供的信息不足以解决问题，这可能需要来回一点，这很好，我很有耐心。
