🧐 问题描述

使用的是 pro-layout 带的 menu , 展开闭合时，非常卡顿，看了下 cpu 占用, 不知道哪一块的问题

💻 示例代码

BasicLayout 文件如下：

/**
 * Ant Design Pro v4 use `@ant-design/pro-layout` to handle Layout.
 * You can view component api by:
 * https://github.com/ant-design/ant-design-pro-layout
 */
import ProLayout, { PageContainer } from '@ant-design/pro-layout';
import React, { useEffect, useMemo, useRef } from 'react';
import { Link, useIntl, connect, history } from 'umi';
import { Result, Button } from 'antd';
import { SmileOutlined, HeartOutlined } from '@ant-design/icons';
import Authorized from '@/utils/Authorized';
import RightContent from '@/components/GlobalHeader/RightContent';
import { getMatchMenu } from '@umijs/route-utils';
import logo from '../assets/logo.svg';

const IconMap = {
  smile: <SmileOutlined />,
  heart: <HeartOutlined />,
};

// 用于为从服务端请求来的菜单添加通过 icon 字段 匹配 Icon （字体图标）
const loopMenuItem = (menuList) =>
  menuList.map(({ icon, children, ...item }) => ({
    ...item,
    icon: icon && IconMap[icon],
    children: children && loopMenuItem(children),
  }));

const noMatch = (
  <Result
    status={403}
    title="403"
    subTitle="Sorry, you are not authorized to access this page."
    extra={
      <Button type="primary">
        <Link to="/user/login">Go Login</Link>
      </Button>
    }
  />
);

/**
 * use Authorized check all menu item
 */

const BasicLayout = (props) => {
  const {
    dispatch,

      dispatch({

        payload: {
          menuParentId: '22248',
        },
      });
      dispatch({
        type: 'dict/types',

  };

  // get children authority
  const authorized = useMemo(
    () =>

  const { formatMessage } = useIntl();
