Validate your payments under
peak load
Simulate realistic high-volume transaction loads across multiple PSPs, test your failover routing under simulated outage conditions, and benchmark P50/P95/P99 latency — before your next peak event causes production failures.
How PayServ load testing works
PayServ generates realistic transaction traffic and routes it through your multi-PSP configuration, capturing latency and failure data at every layer.
Five load test profiles for every use case
Ramp-Up Test
Gradually increase TPS from baseline to peak to identify the inflection point where latency degrades or errors spike. Used to find PSP rate limits and router saturation points.
Steady-State Test
Sustain a target TPS level for 15–60 minutes to validate that your infrastructure handles prolonged peak volume without memory leaks, connection pool exhaustion, or latency drift.
Spike Test
Simulate an instant surge — from normal volume to 10× in seconds — to test how your routing layer handles sudden bursts. Common for flash sale and product drop scenarios.
Failover Simulation
Deliberately trigger a PSP failure mid-test to verify your failover routing activates within target SLAs. Confirms that transactions in-flight are retried on the backup PSP without customer-facing errors, targeting failover in <800ms.
Endurance Test
Run sustained moderate-to-high load for 6–24 hours to surface memory leaks, credential expiry issues, connection pool drift, and PSP API key rate limits that only manifest over extended periods.
Real-time metrics across every PSP
The PayServ load test dashboard surfaces the metrics that matter for your payment team.
