Hi, Hope you are doing well.

This time I have a problem with the server, Currently I am using $15 server which has 2 cores and 2gb RAM, but the performance is poor now I don’t know what is the reason here.

This is the API:

var express = require('express');
var sqlite3 = require('sqlite3').verbose();
var path = require('path');
var router = express.Router();

/* GET users listing. */
router.get('/', function(req, res, next) {

    if(Object.keys(req.query).length === 0){
        res.send("No input given");
    } else {

        let query   = req.query.q;

        let SQLquery = 'SELECT * FROM recipe ';

            SQLquery += 'WHERE RecipeName LIKE "%' + query + '%"';


        let result = [];

        var db = new sqlite3.Database(path.resolve(__dirname, '../recipe.sqlite'));

        db.serialize(function() {
            db.each(SQLquery, (err, row) => {
                if (err) {
                } else {
            }, function(){


module.exports = router;

So basically I have stored data in Sqlite3 which would be 3 Million rows, 280 people or fewer than that, fetching data at a time, but the server is not responding - 100% CPU and RAM.

Help me with this. The structure of script is not good? or $15 server is not enough or what is the problem please explain this.

Thank You!

Hi there,

It sounds like that you might need more CPU power as the application seems to be quite busy.

Another option I could suggest is trying to use MySQL or PostgreSQL instead of SQLite. I would personally use SQLite for local dev environments but whenever performance optimization is hard when using SQLite.
