没能复现哎，你在确认下？

我是笔记本可能处理器比较弱，按住某个键输入时真的很卡，处理器占用很高，vue2.6.x之后都存在这个问题，vue2.5.x没有这个问题。

@Conor-D
Your question is not the same thing.
Your table data is too large, it should be separated from the form into two components, avoid multiple updates. https://codesandbox.io/s/jkmo4927w

I have the same problem.
When the number of tag 'a-form-item' is more than 10 ,problem will be obvious.
You can try it at here,link,quickly enter at 'website' and you will find it.

确实有卡顿问题。尤其用了ant库的组件，在一个页面上达到一定数量时，输入框(不一定是a-input，就算是原始的input用v-model双向绑定)就会输入卡顿。chrome性能分析会发现cpu占用很高。。
