Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Why you should start profiling your application on the production
It's basic, but it works. You can see what function or 3rd library is after your resources and debug them locally (For example, by using ClinicJS - https://clinicjs.org/)

7 Best Tools for Monitoring Node.js Servers
Clinic.js includes three tools to help diagnose and pinpoint performance issues in Node.js applications. It’s surprisingly easy to use. All you need to do is install the module from npm and run it. This will generate reports for you that make troubleshooting much easier.

GraphQL Fastify vs Apollo Server — Learnings from the real world
To compare the two servers, we used two packages. The first one was ClinicJS, an open-source set of tools used to diagnose NodeJS performance issues, which also gives you suggestions and points you in a direction to fix the diagnosed problems. The second one was hey, a CLI tool to send some load to the server. Below we show how we use them and the results of these comparisons.

Assessing memory needs for a running NestJS application
WTF? 1.15 GB of RAM while idle, have you tried to profile the app? maybe you have some memory leaks, use node clinic to diagnose performance issues.

Code Optimisation Doubt, Current code fails to handle concurrent requsts.
You can use https://clinicjs.org along with autocannon to identify bottleneck

Taming the dragon: using llnode to debug your Node.js application
To make things interesting, let’s send some requests to this server with autocannon:

Benchmarking Deno vs Node with GraphQL
Using autocannon, I did the following script to simulate 500 concurrent connections over 30 seconds:
-
A first look at Bun: is it really 3x faster than Node.js and Deno?
We then used autocannon to measure the throughput (requests per second) of each runtime server-rendering our React app.
-
Can we use Pydantic models (Basemodel) directly inside model.predict using FastAPI, if not why?
You could also use tools like autocannon to see how many requests/second you can achieve with various methods. : https://github.com/mcollina/autocannon

How to Use Source Maps in TypeScript Lambda Functions (with Benchmarks)
I used autocannon to test the function at 100 concurrent executions for 30 seconds. I also used Lambda Power Tuning to find the ideal memory configuration, which proved to be 512MB. All the results are available.

Find bottlenecks in Node.js apps with Clinic Flame
Moreover, if your blocking issue is appearing only on heavy load, you can easily test it using the very nice --autocannon CLI param (see it with clinic flame --help) where you can specificy autocannon options to generate some HTTP load on your web service.

Created a URL shortener in Node (Fastify) and in Go (net/http). Why isn't Go faster?
I packaged them both with Docker and deployed them to an EC2 instance, each behind an Nginx reverse proxy I setup in docker-compose. I'm currently testing performance using autocannon from my laptop like this: `autocannon -a 5000 -w 10 URL` (5000 requests with 10 workers), and both apps complete in around 40 seconds. The EC2 instance is in Oregon and I'm testing from Toronto.

DB query performance options.
You can test it by yourself using console.time(). You can use autocannon to stress-test your http server to see what is really the best options.

Experiments in concurrency 3: Event loops
When I test this with autocannon making three simultaneous requests (autocannon --connections 3 --amount 3 --timeout 10000 --no-progress http://localhost:5678/):
