What is a Load Test? A Load Test is a type of non-functional test which verifies the performance of an application or system under a peak user/volume condition. This test also validates the resource usage, stability and reliability of the software system under peak load. What is Peak Load? Peak Load is the highest load … Read more
Performance testing is a systematic testing approach to validate the performance of an application under load. Following are the different type of performance testing:
YouTube Video: Performance Testing What is Performance Testing? “Performance testing is a systematic testing approach to validate the performance of an application under load.” In the above definition, two important words appear. One is ‘Performance’ and another one is ‘Load’. The word ‘Performance’ refers to the behaviour of an application in terms of responsiveness and … Read more
Linux server performance monitoring through the ‘iostat’ command provides general information about disk operations and related statistics. ‘iostat’ stands for ‘Input/Output Statistics’ and it is a utility that monitors system input/output by observing the time the devices are active in relation to their average read and write rates. The output of the command ‘iostat’ helps … Read more
Linux server performance monitoring through the ‘mpstat’ command, is one of the oldest and most valuable ways to capture CPU statistics. If the system is a multi-core processor, then the mpstat command helps monitor each core CPU. If a Linux kernel has dual processors with dual cores, the command will report 4 CPUs statistics. The … Read more
Linux server performance monitoring through the ‘vmstat’ command, is one of the oldest and most valuable ways to capture memory statistics. ‘vmstat’ stands for ‘Virtual Memory Statistics’ and it is a utility that provides an excellent low-overhead view of system performance. Because ‘vmstat’ is such a low-overhead tool, it is practical to keep it running … Read more
