PerfMatrix Latency, Throughput, Bandwidth and Response Time; somehow these terms are very confusing. A new performance tester faces difficulty to understand these terms without examples. This article will help to get the knowledge of Network Latency, Network Bandwidth, Data Throughput and Response Time. So, let’s start now, Look at the above figure (Figure 01). The illustration … Read more
Think Time and Pacing have significant importance in Performance Testing. They are very basic terms which are specially used while designing the workload in the workload modelling phase of PTLC (Performance Test Life Cycle). They are used to control the transaction rate during a load test but have significant differences. A new performance tester is … Read more
Many performance testers do not know the importance of Standard Deviation in performance testing and hence give less attention to it. Standard Deviation is a key metric in performance test result analysis which is related to the stability of the application. The calculation of Standard Deviation is a bit complex and the probability of making … Read more
YouTube Video Link: 90th Percentile in Performance Testing ‘Percentile’ – a common but most important term, especially in performance testing. From the day first when we started analysing any performance testing report, we heard about the 90th percentile. Even our mentor gave more stress on the 90th percentile figures for response time. So, what is this 90th percentile exactly? … Read more
Response time refers to the time that elapses between when a user hits a button on the webpage and the full data received from the server at his end. This is also called End-to-End response time. As a performance tester, you can see response time as a single unit. But the response time figure is … Read more
Difference Between Concurrent Users and Simultaneous Users. Concurrent Users do parallel activity (may be different). Simultaneous Users do same activity.
