Apache JMeter is an open-source tool which is widely used for Performance Testing. The test execution through the JMeter tool is an easy task, but the execution steps also have some best practices to avoid misconfiguration and help to get accurate results. These best practices are listed below:
After getting the issues during the performance testing, we would require an approach for debugging the Performance Bottlenecks. Debugging a web application that crashes under high load necessitates a methodical approach to finding and fixing the underlying issues. Following are some well-defined steps for effectively debugging the performance issues. Performance Bottlenecks Debugging Approach Some Important … Read more
As you know the Garbage Collection shouldn’t happen too soon or too late, because in both cases the performance of the system gets affected. A delay in GC cycles results in memory leakage, whereas too many GC cycles reduce system performance and increase CPU usage. Along with this we also need to understand how much … Read more
These Performance Testing and Engineering Interview Questions may act as a booster for a fresher to grab quickly the basic understanding of performance testing, testing tools and engineering concepts. For an experienced performance tester or engineer, these interview questions will help to recall the basics that they have already learned. Following are the Interview Questions: … Read more
Parallel Garbage Collector or Throughput Collector has an argument to set the target application throughput. The argument is: -XX:GCTimeRatio=<N> To set the target throughput, you need to calculate the correct GC Time Ratio value and input in the file. The below calculator helps you to calculate the correct GC Time Ratio value (N) on the … Read more
When it comes to the memory management of a software application, garbage collection is crucial. Actually, the memory of unused or unreferenced objects is recovered by a Java program called Garbage Collector. It means that, like other Java codes, the GC executes when a certain condition, such as memory fullness, is met. GC affects the … Read more
