Testing

Introduction

Grafana K6 is a highly efficient load testing tool built with JavaScript (with a Golang core) that maximizes the load capabilities of a single machine. According to the official documentation, a single K6 process can effectively utilize all CPU cores, and under ideal conditions, it can simulate 30,000–40,000 virtual users (VUs). This is typically sufficient to handle 100,000–300,000 requests per second (RPS), translating to 6–12 million requests per minute. It enables more efficient load testing without requiring additional hardware resources.
