![]() ![]() Stress testing is a subset of performance testing that involves overloading a system’s existing resources with more tasks than it can manage with the aim of making the system fail. You can also use load tests to reveal current system capacity, bandwidth issues, load balancing problems, and more. The purpose of a load test is to expose defects, such as memory mismanagement, buffer overflow, and memory leads. ![]() Load tests can also reveal how much pressure can be put on a system before performance begins to suffer. You might also leverage load testing by giving a system an empty task, so you can monitor and assess how your VM or system copes with zero-load instances.Ī typical load test will monitor key attributes and metrics, including peak performance, server throughput, adequacy of the H/W environment, and how response times vary based on load levels. Load testing is a highly effective way of determining how much a system or VM can withstand because it pushes them to the limit and monitors the results. Load testing is also different from endurance testing, which assesses how much VMs or systems can cope with by subjecting them to a high load for a sustained time period. Although similar, load testing is not to be confused with volume testing, which is usually for testing databases. If you’re leveraging the right VM performance tools, you can conduct load testing quickly and efficiently. Load TestingĪ load test is a VM performance test type for assessing VM performance by continuously and steadily increasing load until the VM’s capacity has been reached. If your VM performance tests are effective, it will enable you to project VM performance issues. Although many benchmarks are industry-specific, and are certainly worth considering, your business’ benchmarks should be tailored to your individual business needs and reflect service level agreements (SLAs.) Your VM performance test benchmarks should cover resource usage, throughput, speed, stability, and response time. The goal of VM performance testing is to determine an appropriate performance benchmark. Because of this, the phrase “performance testing” can be used as a broad term but also refers to more specialized test types. There are different performance test types, including spike testing, endurance testing, volume testing, and scalability testing. VM performance testing typically involves validating scalability, reliability, and resource usage. Performance TestingĪdministrators leverage VM performance testing to assess how various system components cope with different circumstances. These include performance testing (as an umbrella term), load testing, and stress testing. Three key test types should be leveraged during VM performance optimization activities. A VM performance test can help businesses identify where VM performance issues originate. VM performance tests play a crucial role in improving and maintaining VM performance.
