Slow down the response when using store in passport session Nodejs, Angular

Question

I am using passport for authenticating local user in nodejs and angular.
I am using connect-mongo for storing session.

but when i am using store, my application getting slow response from nodeJs server.

import MongoStore from "connect-mongo";
import { NextFunction, Request, Response } from "express";
import session from "express-session";

const sessionMiddleware = (req: Request, res: Response, next: NextFunction) => {
    return session({
        name : process.env.DAILYMEET_SID,
        secret : process.env.SESSION_SECRET || "",
        resave : false,
        saveUninitialized : false,
        cookie : {
            maxAge : 36000000,
            httpOnly: false,
            secure : false
        },
        store : MongoStore.create({
            mongoUrl : process.env.DB_URL
        })
    })(req, res, next);
};

export default sessionMiddleware;

I am using this code to store session.
