我在autorun Block中调用calendar.refetchEvents();以确保调度程序的反应性（我正在使用资源视图），当使用大数据集进行测试时，尽管我确保只下标2周的部分值事件发生得非常缓慢。
我的事件不是基于Json，我正在使用meteor，我循环遍历日历的Events函数内的事件。 我缺少一些好的全日历练习吗？

答案 0 :(得分：3)
我可以看到你应该优化的许多非流星图案：
this.autorun会在Schedules集合中的任何更改以及各种用户对象更改时重新运行（不仅仅是登录用户，还包括其他用户）。您的自动运行每次都从头开始重建客户端数据，包括大量连接。您可以使用local collection来缓存已连接的数据，然后仅在基础持久文档更改时添加/更改这些文档。这可以使用observeChanges模式完成。或者您可以对数据模型进行非规范化以避免所有这些连接。Session个变量并重复使用它们。这些可能很慢，因为它们使用浏览器本地存储。你应该只将.get()这样的数据放入局部变量一次，然后从那时开始引用局部变量。Schedules出版物中包含字段。其余的都是开销。
