A 100GB/s load-test rig
A distributed load-test rig generating 100GB/s at peak, so capacity and reliability decisions came from measurements rather than guesses.
We needed to know how the platform behaved under real traffic spikes before customers delivered them.
The rig had to generate enough traffic to genuinely stress a platform built for 50TB days — small synthetic tests would have proven nothing.
I implemented a load test framework on K6 and K3s/K8s capable of sending over 100 GB/s of traffic, emulating real-world spike patterns.
Performance, reliability, and scalability were verified under realistic conditions — capacity decisions were made from measurements, not guesses.
// spikes rehearsed here, not discovered in production
- — A self-managed K6/K3s fleet is more upkeep than a load-testing SaaS, in exchange for full control of traffic shape and scale.
- — Synthetic traffic approximates real users, never equals them — results were treated as bounds, not guarantees.
