Dragging is very slow with many DOM items on page

Question

React DnD doesn't appear to scale well.

I have a list of five hundred drop targets and it take several seconds to pick up an element.

Is there anyway of speeding this up?

The list scrolls perfectly smoothly.

我正在使用react-virtual来减少现有DOM元素的数量，但不幸的是，绘图性能远远落后于原生渲染。

另外，一个有用的线程......

虽然从技术上讲，你可以将React DnD性能提升到~3000左右   项目，没有办法让它在没有任何一点之后不会滞后   更改API（并使其不太有用）。如果你有成千上万的   行，我认为你应该使用虚拟化列表。
