How to plan high-scale load testing

Learn how to prepare for massive traffic spikes ahead of your next big event, using Gatling’s high-efficiency load generation engine.

📅 Date: December 16, 2025

🕐 Time: 5 PM CET, 11 AM EST

In this live webinar, Heather (DevRel) and Shaun Brown (Product Marketing) will run a real high-scale test against a real website, ramp to a massive number of virtual users, and show you how to trust your results when things get intense.

What you’ll learn

• How injector resources (CPU, memory, network) set the ceiling for your test capacity
• How to calculate the infrastructure you need for your target concurrency
• Why the first minutes of JVM-based test data can be unreliable (and how to fix it with warmup)
• Essential OS tuning for 50k+ concurrent connections (including avoiding ephemeral port issues)

What you’ll see live

• A complete end-to-end test run
• How to scale up safely to high concurrency
• How to tell injector bottlenecks from system bottlenecks
• How Gatling Enterprise Edition automates distributed execution at scale

Who should attend

Performance engineers, SREs, QA leads, and platform teams planning high-scale load tests.
