Following the dynamic development of technologies, numerous applications and IT systems have become a key element of our everyday lives \u2013 from workplaces to daily duties, leisure and entertainment. While using mobile and desktop applications or web browsers, we expect them to work smoothly and efficiently. High performance of IT systems is not only a technological success, but also a key to the user satisfaction. For example, according to a Google survey, 53% of mobile app entries are abandoned if the loading process takes more than 3 seconds. This shows that speed of the systems is really critical for maintaining users\u2019 attention.<\/p>\n

Performance testing<\/a> is a crucial tool used in this process. It enables verification of smooth and effective functioning of apps and systems under diverse usage scenarios. It helps to detect and correct bugs and defects delaying the applications, which means improving customer experience and satisfaction. In e-commerce, where each second of delay may mean loss of income, performance testing has become not just an engineering practice, but a strategic necessity. Amazon discovered that every 100-millisecond delay in the webpage loading may cost 1% of sales, a really huge value for a company of such scale of operations.<\/p>\n

Thus, performance testing not only ensures improved functioning of IT systems, but also directly influences both customer satisfaction and financial results of companies. In the era of digital economy, where competition is measured by a mouse click, the speed and efficiency of applications may never be underestimated.<\/p>\n

What exactly is performance testing and when do we use it? <\/strong><\/h3>\n

Performance testing is a process of verification and assessment of system or application performance under diverse workloads. Its goal is to identify potential problems in the app functioning, such as slowdowns, failures or loss of data. The tests are conducted in order to confirm that the application fulfils set requirements, even in if it is accessed by a larger-than-expected number of users at the same time.<\/p>\n

Performance testing<\/a> may be applied in various sectors, especially for systems, applications and platforms which are subject to sudden increases in the numbers of users due to e.g. seasonality or individual events (such as Black Friday, weekend of promotions, game release or film premiere). Through performance testing we can examine the interactions of the end-users with a given platform or application in the situations of sudden extreme load changes.<\/p>\n

 <\/p>\n

Performance testing is particularly important for:<\/h4>\n
    \n
  1. Web services, to verify if the websites load quickly and efficiently, which translates into higher satisfaction and better experience of end-users;<\/li>\n<\/ol>\n
      \n
    1. Mobile apps, to verify if they run smoothly, regardless of the number of concurrent users;<\/li>\n<\/ol>\n
        \n
      1. E-commerce systems, to ensure that e-shops will be able to serve increased customer traffic in the peak seasons, such as Black Friday, sales, special promotions or pre-Christmas period;<\/li>\n<\/ol>\n
          \n
        1. Business applications, to identify their transaction capacities;<\/li>\n<\/ol>\n
            \n
          1. Computer games, to guarantee their smooth run and provide highest level of entertainment;<\/li>\n<\/ol>\n
              \n
            1. API, to test diverse request levels and measure response times for their compliance with the set requirements;<\/li>\n<\/ol>\n
                \n
              1. VoD platforms, to assess how they deal with high user traffic during live broadcasts for large numbers of concurrent viewers;<\/li>\n<\/ol>\n

                IoT \u2013 performance testing may include also security issues, such as DDoS attacks or unauthorized access attempts.<\/p>\n

                Performance testing helps to avoid costly problems related to loss of customers or damage of the company\u2019s reputation. This is why you should make sure that your systems and applications work flawlessly, regardless of the load, as this is crucial for your brand\u2019s image.<\/h4>\n

                The specialists conducting performance tests try to answer the question, how long a system or application can run effectively under an increased workload caused by a large number of concurrent users. Their aim is to identify potential causes of failures and provide recommendations how to improve the system\u2019s work and develop contingency solutions.<\/p>\n

                What does performance testing entail?<\/strong><\/h3>\n

                Let us now discuss what elements may be verified by the performance testing and what information it may provide.<\/p>\n

                1. Speed of work:<\/strong> performance testing helps to determine the time of the system\u2019s response to diverse types of users\u2019 queries. It is a key element to ensure competitiveness and user satisfaction.<\/p>\n

                2. Identification of weak spots:<\/strong> performance testing aims at identification of the weak spots in the system which may lead to failures or performance drops in the normal use conditions.<\/p>\n

                3. Optimization:<\/strong> owing to performance testing developers may optimize the codes and administrators \u2013 the architecture, to increase effectiveness of the system and reduce the resource consumption.<\/p>\n

                4. Readiness for loads:<\/strong> performance testing enables identification of the maximum system load, which, in turn, helps to develop a system ready to handle sudden changes of the load \u2013 user numbers or data volumes.<\/p>\n

                Some examples of performance testing use may include verification of the internet server performance during rapid increases of traffic, testing of the mobile applications in terms of their speed on various devices, assessment of the efficiency of data management systems in large corporations, or evaluation of the system performance after major modifications.<\/p>\n

                 <\/p>\n

                We must remember also that performance testing is not a one-time task, which may be skipped without any consequences, but a process of continuous improvement. Performance testing prevents failures and helps to resolve productivity problems, which translates into higher customer satisfaction, competitive advantage and overall success of the company. <\/em><\/h4>\n
