Load testing: find your breaking point before users do
Load testing simulates real traffic against your application so you can measure latency, throughput and errors under stress — before a launch, sale, or traffic spike takes you down.
What is load testing?
Load testing sends concurrent requests to your API or web app and measures how it behaves under pressure. Unlike a single ping, a load test ramps virtual users or requests per second over minutes, exposing slow queries, connection limits, and autoscaling gaps that only appear at scale.
Which metrics matter most?
Throughput (requests per second), latency percentiles (p50, p95, p99), and error rate are the core trio. p95 tells you what most users experience during a spike; error rate catches timeouts and 5xx responses that averages hide. Rampstorm streams all three live so you can stop a run the moment things degrade.
When should you run load tests?
Before major releases, after infrastructure changes, when onboarding a new region, or when traffic patterns shift (e.g. a marketing campaign). Recurring weekly or nightly tests against a baseline catch regressions early — a 20% p95 increase week-over-week is a signal long before users complain.
Cloud vs. self-hosted load testing
Tools like k6 and Locust are powerful but require writing scripts and operating distributed agents yourself. Managed platforms remove infra overhead but often bill per VU-hour with surprise costs. Rampstorm targets the middle: a polished cloud UI, real-time charts, and verified targets — without forcing your whole team to write JavaScript test scripts.
