What Is Load and Performance Testing?

Performance testing involves examining the responsiveness, speed, and stability of an application and ensures that a computer, device, network, or software application performs as expected while under specific workload conditions. Performance testing services help in optimizing resource allocation, ensuring compliance with SLAs, and improving system stability. A strong performance testing strategy includes tests that evaluate the reliability, processing speed, data transfer rate, throughput, network bandwidth, and affordable load limit through various performance testing activities.

Load testing ascertains how well the system can manage the anticipated load and spot any bottlenecks, performance problems, or scalability constraints. Our load testing services validate system scalability by assessing how well the infrastructure can handle increasing user loads. To evaluate a software program, system, or website's performance and behavior under typical and peak load situations, load testing services mimic heavy workloads and high traffic volumes on the target system or website.
