Full-Service Website Load Testing

Load testing is the practice of simulating activity on your website and applications to see how they perform. It’s a smart way to ensure you’re ready for launch or peak traffic, plus know how many users you can handle at acceptable page loads.

If your testing needs are complex or you simply need extra resources, our professional services experts can help. Your lead engineer will work with you throughout to gather requirements, define scenarios, run tests and review results. You’ll identify issues like bandwidth limitations, error rates exceeding thresholds and server CPU limitations.

Typical Metrics Used
