Software Performance Testing: Important Metrics to Track

by Tech Geekk writer
QA performance test engineers love categories to measure metrics. 
The parameters and measurements collected when a software undergoes the quality assurance process, i.e. metrics, are used to understand the efficacy of performance testing. What that means is that the metrics serve to demonstrate the software’s performance when subjected to real user scenarios and how well it manages user flow. If you are still not sure about metrics, here are some other reasons why they are important: 

a. Metrics enable the team to better keep an eye on the project’s progress at all times.
b. The use of metrics empowers QA teams to quickly and easily identify an issue and then measure it with the aim to determine a solution to address the aforementioned problem.
c. In the long run, diligently tracking performance metrics allows QA teams to compare the results of different tests and then use the insights thus gained to at least roughly calculate the impact of changes made to the code.

Now that we know why performance testing metrics are important, it is time to walk you through some of the most important metrics the QA team must keep a close eye on: 

  1. Requests per second: The client app creates an HTTP request and sends it to a server which, in turn, processes this request, initiates a response which is sent back to the client. The metric here, then, is the total number of requests per second  and these can be requests for any data source, be it multimedia files, HTML pages, XML documents, or JavaScript libraries among other things.
  2. Virtual users per unit of time: This metric is concerned with determining if the performance of a software product is in sync with the requirements specified under the purview of the project. This metric enables QA teams to gauge the average load and software performance under various load conditions.
  3. Average load time: The average load time is used to get an idea about the software’s quality. In case the software takes too long to load, the QA team will analyze the average load time and offer suggestions about different areas of improvement.

Let us wrap this up with a quick look at the parameters that must be evaluated under the purview of performance testing metrics: 

a. Memory usage: This refers to the amount of physical memory being used to process the requests.
b. Response time: This parameter refers to the total time taken, starting from the request until the first character of the response is received.
c. Database locks: This parameter refers to the locking of databases as well as tables that are tracked and regulated meticulously.

If you are thinking that you could make do with tracking performance testing metrics simply because it is a good idea to do so, you are missing the point. As the above discussion demonstrates, these metrics can help take your software’s quality to the next level. It may also help to keep in mind that metrics offer valuable insights to optimize vulnerabilities. Anyway, now that you have a fairly decent idea about software performance testing parameters, you can go ahead and get started on putting together a robust process. Alternatively, you can engage the services of a trusted service provider to help you navigate the performance testing process.
