PFLB

PFLB is a performance and load testing company. Since 2008 our 150+ performance engineers have run load, stress and reliability testing for 300+ companies - banks, retailers, SaaS vendors and public sector systems.

We find the limit of a system before its users do. Load profiles are built from real traffic, peak conditions are reproduced on a test bench, and the bottleneck is reported with numbers: which component gives way, at what concurrency, and what it takes to fix.

Typical engagements: core banking under seasonal peaks, e-commerce before a launch or a sale, cloud migrations, and independent benchmarks commissioned by vendors who need an unaffiliated lab to measure their own product.

Performance testing is our full-time specialty, backed by our own cloud load testing platform with AI-assisted script generation and reporting. That is why a first result can arrive in days rather than months.

Around it we also cover functional testing, test automation and integration testing - for a single release or as an embedded QA team.

SOC 2 Type II certified and ISO 27001 compliant, headquartered in Wilmington, Delaware. 37 published case studies with the numbers are at pflb.us/cases/
