Performance testing is conducted for providing information to the stakeholders about the speed, capability, reliability and scalability of the application. These help in identifying what needs to be done for improving the application before it goes to the end-users in the market.

• If the application was released to the market without conducting performance testing, then the issues such as slowness in software, application inconsistencies, application crash under the influence of heavy workloads would not be detected.
• Performance testing helps to determine if the application meets the performance REQUIREMENTS under varying workloads. If an application with poor performance attributes is launched to the market, then it can lead to a bad reputation and loss in sales.
• Whenever we are DEALING with mission-critical applications or life-saving systems, then it is very much necessary to conduct performance testing so that the application behaves consistently for a long period.
• Just a 5-minute downtime of Google.com in the year 2013 resulted in losses of $545,000. According to LovetheSales.com, a downtime of YouTube for 37 minutes cost Google around $1.7m in losses in ad revenues in the year 2020. According to GREMLIN, Amazon.com loses $13,219,128 PER HOUR due to downtimes. We can see the revenue impact of software downtimes on the companies.

Hence, performance testing is very much crucial before any application is launched to the market.
