 About us

Performance testing is the testing practice performed to determine how a system performs in terms of responsiveness and stability under a particular workload. It is one of the quality controls implemented by software quality professionals to help ensure maintain consistent working conditions of a platform, object, application or tool. With increasing demands and requirements being placed on the software products and projects, PtU aims to help pave the path to a global standard in this area of expertise.
