Frequently asked questions

Common questions about load testing and how LoadForge helps.

What is load testing?

Load testing is the practice of simulating concurrent users hitting your application to measure how it behaves under realistic and peak traffic. It helps you find performance bottlenecks, capacity ceilings, and broken assumptions before users do.

Why should I load test my application?

Load testing catches performance regressions and capacity issues before they cause outages, missed SLAs, or lost revenue. It is especially important before launches, sales events, marketing pushes, infrastructure changes, and database migrations.

Which framework or platform does LoadForge support?

LoadForge can load test anything that speaks HTTP, HTTPS, WebSocket, or any TCP-based protocol — including REST APIs, GraphQL, gRPC, web frameworks like Rails, Django, Laravel, Express and Spring Boot, e-commerce platforms like Shopify and Magento, databases through their HTTP interfaces, and AI inference endpoints.

Do I need to write code to use these guides?

Most of these guides include ready-to-paste Locust Python scripts. You can run them as-is on LoadForge or adapt them to your endpoints. LoadForge also has a script builder if you prefer a no-code starting point.

How do I pick the right number of virtual users?

Start with realistic traffic — usually 1.5x to 2x your current peak — and ramp up from there. Each guide in this section walks through a sensible starting point for the technology in question, including how to model think time and concurrency.
