Bottleneck identification is an art in Performance Testing. Without knowing this art you can not be a perfect performance tester. There are certain performance test result analysis technics which help to conduct a proper approach to find the bottleneck and its cause. Before starting an investigation on the bottleneck, you can apply the WHIWH rule. WHIWH rule suggests a … Read more
Network-side performance result analysis is a follow-up to Client and Server performance analysis and tuning efforts that I have discussed in the previous articles (Performance Test Result Analysis Basic Level and Performance TestResult Analysis Intermediate Level). Once you tested and optimized the client and server-side performance but still not getting the desired result, then look at the … Read more
This is one of the basic graphs and frequently use to debug the performance bottleneck. The error graph provides details about the type of errors and the time when they occurred. Error graphs could be the first point to kick off the investigation of performance issues. It helps to categorize the error using the response … Read more
This has been noticed that the throughput graph is always less attentive. The reason could be that a performance tester does not understand its importance or does not care about it because it is not included in the NFRs. Of course, it is true that Throughput does not fall under the core performance metric category … Read more
In a performance test script, a transaction refers to a group of requests which are sent to the server. A simple webpage may contain multiple requests which are associated with the components available on it. When a user does any action like hitting a button on the webpage then these requests (sync or async) are … Read more
Response time graph gives a clear picture of overall time including requesting a page, processing the data and getting the response back to the client. As per PTLC (Performance Test Life Cycle), the Response time NFRs should be discussed and agreed upon during the NFR gathering phase and then compared with the actual response time … Read more
