Performance Tuning in Node.js

I am developing a custom software project. What are the most effective strategies for performance tuning in Node.js applications, specifically in terms of optimizing event loop processing, managing memory allocation, and enhancing asynchronous operations for large-scale and high-traffic applications?

What part of the system is slow? You can’t preemptively do what you’re asking, you need to know exactly what the issue is you want to tackle before you even think about tuning it. You probably don’t want to be doing that stuff with Node. For example, if it’s really important that you have to manage the memory, use a different language
