[aditya-padhi-kbl]

• I have searched the issues of this repository and believe that this is not a duplicate.

Reproduction link

https://stackblitz.com/edit/react-ofcadv-gcds33?file=index.js

Steps to reproduce

Step 1:-
Visit the above url (https://stackblitz.com/edit/react-ofcadv-gcds33?file=index.js).

Step 2:-
In index.js goto line no 129
Change the perfMode to false

Step 3:-
Click on the input box to reproduce the issue.

Observation

1. The component takes a while to render
2. Key-strokes on the select component takes a while and then the transfer component is displayed in the UI.

Step 4:-

1. In index.js goto line number 15
2. reduce the count to 400

Observation:-

1. The component renders quickly
2. Key-strokes on the select component is very fast

What is expected?

There is should not be a lag while rendering the transfer component

What is actually happening?

I could see a lag while when the item count is greater than or equal to 1000

Environment	Info
antd	3.26.13
React	16.13
System	MacOS
Browser	Chrome

In the same StackBlitz link I have added react-window component. It can be enabled by setting the perfMode to true .
It will be good if FixedSizeList could be easily integrated with antd transfer component
