NextJs router seems very slow - reactjs

Question

The problem is about that is taking long time to response another route. It seems next router's error and it can cause by this ("getServerSideProps"). How can I change with this code to another or did I need to change react router instead? This is index which used ("getServerSideProps") -
import axios from 'axios';
import VideoCard from '../components/VideoCard';
import { BASE_URL } from '../utils';
import { Video } from '../types';
import NoResults from '../components/NoResults';
interface IProps {
videos: Video[];
}
const Home = ({ videos }: IProps) => {
return (
<div className='flex flex-col gap-10 videos h-full'>
{videos.length
? videos?.map((video: Video) => (
<VideoCard post={video} isShowingOnHome key={video._id} />
))
: <NoResults text={`No Videos`} />}
</div>
);
};
export default Home;
export const getServerSideProps = async ({
query: { topic },
}: {
query: { topic: string };
}) => {
let response = await axios.get(`${BASE_URL}/api/post`);
if(topic) {
response = await axios.get(`${BASE_URL}/api/discover/${topic}`);
}
return {
props: { videos: response.data },
};
};
This is from another code with that used next router
import React, { useState } from 'react';
import { NextPage } from 'next';
import { useRouter } from 'next/router';
import Link from 'next/link';
import { AiFillHome, AiOutlineMenu } from 'react-icons/ai';
import { ImCancelCircle } from 'react-icons/im';
import SuggestedAccounts from './SuggestedAccounts';
import Discover from './Discover';
import Footer from './Footer';
import useAuthStore from '../store/authStore';
const Sidebar: NextPage = () => {
const [showSidebar, setShowSidebar] = useState<Boolean>(true);
const { pathname } = useRouter();
const { fetchAllUsers, allUsers }: any = useAuthStore();
const activeLink = 'flex items-center gap-3 hover:bg-primary p-3 justify-center xl:justify-start cursor-pointer font-semibold text-[#F51997] rounded';
const normalLink = 'flex items-center gap-3 hover:bg-primary p-3 justify-center xl:justify-start cursor-pointer font-semibold rounded';
return (
<div>
<div
className='block xl:hidden m-2 ml-4 mt-3 text-xl'
onClick={() => setShowSidebar(!showSidebar)}
>
{showSidebar ? <ImCancelCircle /> : <AiOutlineMenu />}
</div>
{showSidebar && (
<div className='xl:w-400 w-20 flex flex-col justify-start mb-10 border-r-2 border-gray-100 xl:border-0 p-3 '>
<div className='xl:border-b-2 border-gray-200 xl:pb-4'>
<Link href='/'>
<div className={pathname === '/' ? activeLink : normalLink}>
<p className='text-2xl'>
<AiFillHome />
</p>
<span className='capitalize text-xl hidden xl:block'>
For You
</span>
</div>
</Link>
</div>
<Discover />
<SuggestedAccounts
fetchAllUsers={fetchAllUsers}
allUsers={allUsers}
/>
<Footer />
</div>
)}
</div>
);
};
export default Sidebar;
