Performance Testing Metrics: A Complete Business Guide

The level of performance an application or website offers its users is one of the most important factors in evaluating whether or not it will be successful in meeting the demands of today's mission-critical businesses (UX). These commercial apps should be free of any performance bottlenecks, such as slow loading times, frequent time-outs or crashes, poor response times, and the like. Web applications and mobile apps need to be scalable, reliable, and robust in order to give an efficient performance to end users. For this reason, performance testing is very necessary in order to guarantee that mission-critical apps run without a hitch.

Quick reminder: if you need performance testing services or the services of a qualified UAT company, you can always contact UTOR.

And now, let's find out in more detail what service performance is, and why performance testing measurements are so important.

Performance testing – what is it?

Performance testing is a non-functional software testing technique used to evaluate an app's or website's responsiveness, dependability, scalability, and speed. A spike, volume, endurance, stress, load, and other testing techniques for performance are available. These performance test methods aid in determining how well an application performs under a range of network conditions, user loads, bandwidths, etc. Performance testing metrics, commonly referred to as key performance indicators (KPIs), are used to assess the efficacy of this testing approach by the performance testing company. These KPIs specify how well performance testing for firms have worked.

Performance testing metrics explained

Performance testing metrics are any measures or parameters that are obtained during the various load and performance testing techniques. These metrics make it possible for performance test engineers or quality assurance teams to evaluate how successful the performance testing process is and to more precisely identify the major aspects of the product that need further attention or improvement.


Why are performance testing measurements necessary?

  • Describes the present state of the application's performance together with that of the network and the infrastructure.
  • Compares the results of the tests and provides assistance with the impact analysis of code changes
  • a comprehensive analysis of the performance testing procedure's efficiency is carried out here.
  • Provides QA teams with the ability to make informed decisions, resulting in improved software quality.

A crucial performance test measure

CPU utilization: This is the proportion of the CPU's available power that is used to handle requests.

Memory usage: This indicator shows how much of the computer's main memory is being used to handle all job requests.

Response times: This is the amount of time it takes to get a response after making a request. The website or application will operate better with a faster response time.

Average load time: This statistic gauges how long it takes for a website to finish loading and show up on the user's screen.

Throughput: Also known as the rate at which a network or computer gets requests per second, it represents the number of transactions a program can process in a second.

The length of time a request spends in a queue before being processed is known as average latency or wait time.

A measure of bandwidth is the amount of data transmitted per second.

Requests per second: This measure describes how many requests the program responds to each second.

Error rate: The ratio of requests with errors to all requests is known as the error rate.

Transactions Passed/Failed: This statistic represents the proportion of passed/failed transactions to all transactions.
