Performance testing, by its name itself, is to scrutinize the quality of a product – hardware or software in terms of its speed, efficiency and effectiveness. The product might contain a comprehensive set of features in the way to attract the users. At the end, it’s all about the bottom line stating how fast the product features works – yes the response time matters when a user interacts with the product. When the product is slow even though it has features comfortable to user or what he wants exactly from the product, it has the potential to go failure just because it ‘s not triggering the output as fast as the user expects. Needless to say in this fast-moving technology world, people want their daily happenings instant and easy to move the life going on and on from modular kitchens & toiletries to finding their life partner matches.

The performance is evaluated for a product’s particular feature when the functionality is stuffed with certain amount of load and stress - and so the load and stress testing goes in conjunction with performance testing. The performance of a product feature accounts to its enduring capabilities under an expected amount of load, which is gradually increased, thereby allowing the product to experience stress when the load applied is beyond the limit.

The output response time is measured for every application of load to determine what amount of load creates hindrance to the normal operation – arrive the maximum limit of load to assess if the application is able to adequately perform when the upper-limit load takes off to higher levels – in one line, to compute how far the application is robust at times of overload or extreme load conditions.
