poll 是指每秒检查多少次,是值越大频率越大。

@gwuhaolin
Turn on polling by passing true, or specifying a poll interval in milliseconds:

module.exports = {
  //...
  watchOptions: {
    poll: 1000 // Check for changes every second
  }
};

文档说明的是interval,示例中interval是1000,为1秒,所以是每秒poll一次
是interval,并不是频率,如果是频率,上面示例就是1000次了

这里可以看到这个poll是直接传递给setInterval的
