Can NODE.JS Server Handle 1M Concurrent Requests? | Real-World App Benchmarking on Dedicated VPS

Ever wanted to push the limits of your Node.js Server and see what can really Node.js Handle? In this video we will push the limits of a Node.js/Express.js Server that is built with Login/Register and Authentication and some interesting calculation functions to see how can it operate when it comes to thousands of concurrent connections and millions of requests. We will stress test using 1K, 10K, and 1M concurrent connections connected to the server at the same time and sending requests to the server from a simple HTTP GET Homepage to random login/Register API stress test throughout the HTTP Protocol and see if really Node.js can handle 1M requests/s?

That was quite interesting and very insightful. Thank you !

[@lunix8028]

Loved the content man, thank you very much!

[@mdshadab3470]

Bro you just rock. This video worth watching really 🔥🔥🔥

[@raymondmichael4987]

I'll rewatch this; Thanks brother

[@neelthakkar4492]

Seriously underrated channel. But don't worry you are going to get 100k+ in nearby future.

[@namaefumei]

Learned a lot. Thanks!

[@LukasSkywalker_]

If there is a database, it will almost always be the bottleneck. Caching, indexing, etc helps. Not the porpouse of this video, but running multi nodejs instances with pm2 or k8s is a good way to scale also. I'm a software engineer for a bank. We have a lot of unique and concurrent users (I'm not allowed to say the exact number but it is way above the tests of this video) and the main service is powered by node. It is handling well at most cases, with the things I mentioned previously. It is not the most performant language/VM but is good enough.

[@kevinjimenez6143]

You use Typescript?

[@oussamasethoum2755]

Good information, Thank you.

[@akeemovic]

Great job! 👍 Please make a NodeJS scaling tutorial.

[@mahendranath2504]

Thank you So much 👍🏼🙏🎉❤️

One of the most underrated KZbin channel .

[@kienang7850]

Hi, if we use nodejs cluster, can it do better?

[@oktachandra1851]

have you tried nodejs cluster combine with worker-thread to load heavy concurrent requests ?

[@ziyaasgarov6973]

Thanks for the video. Could you please suggest which programming language/framework would be the best for handling heavy tasks on the backend side?

[@arpitabali3621]

which version of node have you used in this video??

[@longnguyenthanh6876]

thanks

[@dheerajkukreja4269]

How are you printing the response status and latency in terminal....please reply

[@mdsamir8495]

Awesome

amazing

How to scale node js app

[@mohamedyoussef8835]

Awesome video ++++++++++ 🙂

[@gasacchi6734]

Maybe you can run the benchmark on your local machine, so VPS doesn't allocate ram for running benchmark, btw nice video ❤️

[@Cdswjp]

Would that be a bad idea resulting in inaccurate test results because the local environment does use the same hardware configurations as the VPS…. Or does it…? 🤔

[@teetanrobotics5363]

Could you please make 2 playlists for: 1) nodejs tutorials 2) react/nextjs tutorials ? Amazing content. thank you

[@tyongalves7129]

bruv thanks so much

[@adityasethi9794]

nodejs is not single threaded. Hate it when people make such vids pretending they know it fully. JS is single threaded. Nodejs is not a language, it is a runtime. it makes use of threads too.

[@kanehooper00]

Yes totally agreed. The tool being shown at the beginning is for browser runtimes and not Node.js runtime. The benchmarking is fine but the fundamental understanding of Node is not quite right.

[@JohnDoe-ji1zv]

When you ran benchmark on your server and local machine you were actually utilising only 1 core of the CPU. Would be much better if you scale node at least with pm2 on local machine and VPS as well, then results would be slightly better.

[@Cdswjp]

Good catch. How were u able to notice that?

[@JohnDoe-ji1zv]

@@Cdswjp by default node is running on only 1 core, so to scale node you need to create an instance per core

[@soniablanche5672]

you can also use cluster to have multiple express apps running on a different core

[@AyushKumar-te7jn]

@@soniablanche5672 pm2 is far better and easier

[@mohamedelsayed1868]

pm2 + worker threads

[@7heMech]

Would be good if you use multiple threads.

[@sumitsharma5946]

Shouldn't you run benchmark on your server(Sever api endpoint) from your local machine instead of logging in to ssh?

[@soniablanche5672]

it will probably cost him a lot if he pays by request for the VPS lol

[@soniablanche5672]

what about clustering to make use of multiple cores

[@dinoscheidt]

Much better to do this on the system layer. Aka: Typical are 1 core docker containers. Then auto scale the nodes with kubernetes.

[@KuroManX]

@@dinoscheidt just run pm2

[@hanimecheddal6472]

😍😍

hail golang :3

[@Dev-Siri]

Fastify would have actually performed better instead of express. Its about 3x faster than express so it would have been a better fit for this video.

[@hijazi479]

well, most of the time it's the database that causes errors or timeouts.

[@pbdivyesh]

I don't know why, but somehow I could not understand anything in this. PS I have 7 YOE.

The only thing better than this video is making money in cryptocurrency.

[@daksmemes7428]

I think jmeter is better
