Which One Performs Better .NET Core Or NodeJS?

This is a quick walk-through for anyone interested in learning more about what’s going on in these two cutting-edge technologies. I was thinking about the same thing and wanted to know whether there is a true winner.

One thing I saw was how enthusiastically Microsoft supports the.NET core. This is excellent, and the addition of the Microsoft tag has resulted in a professional-level programming environment with supporting tools such as Visual Studio. Building, debugging, and publishing.NET C# code across various platforms and devices has never been easier thanks to Visual Studio.


.NET Core

.NET is a Microsoft-owned open-source software development framework that was later released to the open-source community. It had two branches at first: the.net framework, which works solely on Windows, and the.net core, which operates on all platforms. However, as of.net core version 3, Microsoft no longer supports the.net framework. All future releases will be rebranded as and will only be.net Core versions. NET Core is well-known for its ability to create modern cloud-enabled, Internet-connected programmes.


Node.js is a free and open-source runtime environment for building network applications that are both fast and scalable. Chrome’s javascript runtime, known as the V8 engine, is used to power Node js. Because it uses an event-driven, non-blocking I/O mechanism, Node js is preferred for data-intensive real-time applications. In the development of process-intensive applications like video and audio processing, Node js is not recommended.

Both of these frameworks are open-source and have their own set of advantages and disadvantages. However, to assist you in resolving your quandary, I’ve listed three factors to examine before making a decision.

Request Handling

.NET Core

Prior to version 4.5, it handled requests in the same way that Apache/PHP did, i.e., synchronously. As a result, each I/O process would require its own threads, which would all run in a synchronous manner. This technique has limitations and does not interfere with the Node.js request handling mechanism.

However, since version 4.5, the async/ await pattern of request handling has been introduced, which allows you to manage requests without interrupting the execution of your program. It’s a task-based approach that makes use of callbacks, async/await programming models and promises.

Let’s look at an alternative to Node.js that uses the async method in ASP.NET core to handle incoming requests instead of boilerplate setup code:

using System.Collections.Generic; 
using Microsoft.AspNetCore.Mvc; 
using System.Linq;  

namespace TodoApi.Controllers {     
    public class TodoController : Controller
          public async Task<IHttpActionResult> GetAll() 
                   var client = mongoDB.Connect();
                   var database = client.GetDatabase("example");
                   var collection = database.GetCollection<BsonDocument>("data");
                   return Ok(await collection.Find(new BsonDocument()).ToListAsync());             


The single-threaded callback handler is used by Node.js, whereas.NET now employs asynchronous programming to process requests. The original ASP.NET version, on the other hand, employed an asynchronous pattern.

When you use Apache, each of your requests is handled by a distinct thread pool. Node.js, on the other hand, is single-threaded and responds to your calls asynchronously, without stopping your requests. As a result, Node.js is an excellent solution for I/O-bound applications.

You can use Nginx-load balancing, native Node js clustering, or Node.js process management PM2 to cluster single-threaded request handling, allowing you to use as many server cores as your CPU can support.

The demise of the Node.js single-threaded feature also brings with it a “callback-hell,” which may cause complexity in your work.

See how Node.js asynchronously processes a database query:

const express = require(’express’)
const app = express()
const MongoClient = require(’mongodb’).MongoClient
const url = 'mongodb://localhost:123456/example'
app.get('/', async (req, res) => {
  const db = MongoClient.connect(url);
  const col = db.collection('data');
  const results = await col.find({}).toArray();

When comparing the performance of.NET Core vs. Node.js in terms of request handling, you can see that ASP.NET MVC Core will handle more requests because it works in parallel. However, when switching contexts and using a lot of thread-shared variables, Node.js is superior because.NET might be expensive.

Capabilities of Containers

If you’re considering dealing with containers or containerizing your roadmaps, you should evaluate both the.NET Core and Node.js frameworks because they both have different capabilities.

A Node.js developer may create their app faster and quickly reproduce build components by using Node.js containers. The microservices architecture is implemented in Node.js, allowing for horizontal growth and rapid development. Developers can utilize containerized Node.js apps to scale up or down according to workload requirements in this fashion.

Developers may now deploy and construct desktop, mobile server, and web-based workloads in.NET Core. With ASP.NET Core, you may create a custom runtime environment in Windows or Linux distributions by using Microsoft Nano Server container handling.

Nano Server is a server operating system for private clouds and data centres that may be managed remotely. It’s a small Windows server that can run 64-bit tools, agents, and applications.


.NET Core

  • Separation of concerns is a possibility.
  • With built-in libraries, coding time is cut in half.
  • Security
  • Visual Studio provides a welcoming coding environment and tooling.
  • Support for several platforms
  • Development and deployment across a variety of platforms, including cloud, IoT, and desktop.


  • Is able to communicate in a single language JavaScript is used to construct both the front end and the backend.
  • By default, Node is cross-platform and asynchronous.
  • The use of external modules is supported by the NPM package management.
  • Code modularity reduces internal project dependencies, and exported modules can be reused in different projects without affecting existing code.

Community Support

In 2002, Microsoft released ASP.NET, an open-source server-side framework. .NET Core allows developers to use the standard C#, Visual Basic, and F# languages to create apps and dynamic web pages. This is one of the reasons why the.NET community is so powerful, particularly on Stackoverflow.

Ryan Dahl, an engineer, invented Node.js in 2009, seven years after the release of .NET Core. Node.js allows developers to write back-end code using front-end languages. Node.js has quickly garnered a strong community following due to its simplicity and popularity. It has its own GitHub fan base.

Several well-known companies have switched to Node.js.

PayPal, Netflix, Uber, LinkedIn, eBay

.NET Core has been used by a number of well-known companies.

Chipotle, UPS, GoDaddy, Asgard Systems, Siemens Healthineers

Throughout the investigation, despite the fact that the majority of the benchmarking results were in favour of .Net Core. Things may be dependent on the project’s requirements, as well as hosting constraints. However, I made a note of it. With Microsoft’s support and enterprise-level influence, Net Core has begun to move forward passing node. So, I believe. With all of these benchmarks and cloud support, net core takes the top.

And Node.js is built on top of V8, which is written in C++. As a result, Node has a second layer below it that includes additional effort while compiling the code. However,.NET core generates a.dll that is much closer to machine-readable. Because, in the end, the only thing that matters is how quickly the code is compiled.

I hope you can see how I can accomplish this. Let me know if you face any difficulties.
