我是NextJS的新手，我已经部署到Netlify作为一个生产版本。然而，当我使用next router导航到一个页面时，它需要大约3-4秒才能加载到一个特定的页面。但奇怪的是，它在本地开发环境中工作得很快。

interface Props {
  id: string;
}

const Profile: NextPage<Props> = ({ id }) => {
  const subMenuData: any = {
    posts: '게시글',
    likes: '좋아요',
    // playings: '연주',
    lessons:  '레슨',
    reviews: '리뷰',
    // requests: '레슨신청'
  }

  const [ subMenu, setSubMenu ] = useState<string>('posts');

  const songData: IData[] = [ ...Array(12) ];
  songData.map((v,k) => {
    songData[k] = { title: '너를 만나', artist: '풀킴', rate:4 };
  })

  return (
    <PageRoot className={styles.root}>
      {/* <PageNav className={styles.nav}>
        프로필
      </PageNav> */}
      <PageContent className={styles.content}>
        <div className={styles.profile}>
          <span onClick={() => moveUrl('/profile/update')}>
            내 프로필 수정 <MdArrowForwardIos />

        </div>
        <div className={styles.info}>
          <div className={styles.img}>

        <nav className={styles.submenu}>

  function clickSubMenu(e: React.MouseEvent, key: string) {
    setSubMenu(key);

export const getServerSideProps: GetServerSideProps = async (context) => {
  const props = {
    id: context.query.id
  }

  return {
    props
  }
};

export default Profile;

我将图像设置为延迟加载，但这对减少加载时间没有帮助。
如何缩短装货时间？
