Node.js Low-Level Performance & Concurrency Experiments

This repository contains focused, reproducible Node.js experiments that target low-level runtime behavior: process and stream backpressure, child-process IPC/fd wiring, and V8 optimization pitfalls. The goal is to produce high-signal experiments that help you reason about concurrency and performance tradeoffs with evidence, not assumptions. This is work in progress and I will be adding more experiments in future!

Prerequisites

• Node.js (modern LTS recommended). All scripts are CommonJS.
• Most commands and monitoring snippets are Linux/macOS oriented.
• I will avoid using any node modules and keep experiments vanilla.

Quick Start

Run experiments directly:

node <script-path>

Example:

node concurrency-experiments/spawnYesCommandTest.js

These are standalone experiment scripts, not pass/fail test-suite cases.
