What is Node.js System Service?
Why is Node.js So Prolific?
Node.js has many advantages including:
- It does not block input/output (I/O). I/O refers to data transfer through any operation, program, or device.
- Low-latency, real-time apps respond well with Node.js.
- Node.js is a welcoming community with an open-source mentality.
- Fewer servers are necessary to deliver results with Node.js.
While its speed is remarkable, it's widely used and it functions super efficiently, can Node.js handle high levels of traffic? Just how much traffic can Node.js handle? How many requests per second can Node.js do?
Concurrency is an environment where multiple computations are occurring simultaneously. It is a common occurrence in programming and concurrency scenarios: multiple computers in a network, multiple apps running on one computer, or multiple processors in a single computer. Web-based applications must be able to handle concurrent requests. So how do we handle concurrency?
Another issue is that threading between systems and using a context switch between two threads is a slow process.
Node.js Event Loop
Node to the rescue! To address these threading concerns, Node.js uses a single thread with an event-loop. In this way, Node can handle 1000s of concurrent connections without any of the traditional detriments associated with threads. There is essentially no memory overhead per-connection, and there is no context switching.
The way that Input/Output (I/O) was generally handled when in concurrent use wasn’t ideal. Creator Ryan Dahl identified the problem and came up with a solution.
Node.js Requests Per Second
A benchmark made by Fastify, shows that Express.js— a minimal and flexible Node.js web application framework with a robust set of features for web and mobile— can handle approx 15,000 requests per second and the basic HTTP module, 70K requests per second. This is very fast.
In an engaging article, Davit Vardanyan did his own experiment to test these Fastify benchmarks. He found using a 2015 Macbook Pro he achieved almost similar results. But noted that the published results using Express.js are generally not accurate for a real-world API. To have a real-world API one has to create a handler that communicates with a database or other services. So he set out to conduct his own experiment with a smaller API and did load tests.
He employed Heroku, a $25/mo hardware, and received results of an average of 515 results per second with his Node.js instance. Then using a technology that is not single-threaded, he employed the Django app and achieved results of 389 requests per second on average. Next Vardanyan used his Node.js application as a real production application and deployed it in AWS. He used 3 Node.js instances with AWS load balancing, and these three instances could handle 19k requests in ten seconds, which breaks down to 1858 requests per second.
The result is that Node.js is very fast. While this was one person's experience and experiment it gives an idea of how many requests Node.js is capable of handling per second. Node.js may very well be the right fit for your app if you’re looking for quick, real time data updates. And we all know that immediacy is the name of the game, however, any good developer knows that you cannot compromise integrity and security for speed. This is why Node.js can be such a great tool, when executed correctly, it is fast, delivers results and can be done with proper security.
Finding the Right App Development Partner
If you’re reading this article, chances are you’re either a developer or a very savvy individual creating an app and you want to learn the best coding language to build in. While it depends on what your app’s needs will be, you want to work with a partner who knows the options and can offer you the best technology.
There are many factors to consider that go into a great partnership, including your budget and time-frame. You also want to ensure your development partner has experience in delivering projects similar to yours, the ability to provide tailored solutions that fit your unique business needs, and that there is a culture fit between companies and employees.

Follow that up with an article dedicated to helping you find the right cultural fit for your development needs.
