Overview

iPerf and iPerf3 are industry-standard, open-source network testing tools designed to measure TCP and UDP bandwidth performance across local and wide area networks. Capable of simulating traffic flows under various conditions, iPerf tools help administrators, engineers, and developers assess available bandwidth, detect bottlenecks, and validate quality of service (QoS) policies. Their flexibility makes them equally effective for point-to-point LAN testing, WAN link evaluation, and cross-continental performance benchmarking.

Network Test Pro supports organizations across North America in deploying iPerf/iPerf3 within enterprise, service provider, and R&D environments. Whether integrated into CI/CD workflows, embedded in remote appliances, or used in field diagnostics, our tailored implementations ensure accurate, repeatable results. With Network Test Pro’s expertise, teams can transform iPerf from a standalone tool into a strategic asset for continuous network performance monitoring.
