load performance testing tools

At present, most testers like to use Loadrunner with a graphical interface as a web performance testing tool. In fact, there are many open-source performance testing tools on Linux systems that are very small and open-source products. It is a good choice for testers. In the

ArticleDirectory Crystaldiskmark: Atto disk benchmark: HD tune Pro: Crystaldiskinfo: As SSD benchmark: After purchasing hard drives, SSDS, USB flash drives, storage cards, and other devices, we all want to fully understand their performance, especially the disk read/write speed. Or, after the device is installed, you also want to test whether the read/write speed of the hard disk meets the manufacturer's nominal value. In

PS: Stress testing is an important task in operation and maintenance. For example, before a Web site online, can withstand the number of visits, in the case of large traffic performance, these data indicators will directly affect the user experience. However, there is a common in stress testing, that is, the results of the stress test and the actual

that the overall interaction is 6W per second and 6W receive, and the resulting bandwidth up and down line is 60MB, which basically has the test environment 1Gb bandwidth ran out. This is true from the system's resource manager. Test Case 2This test mainly set the message sent to 4K, because of the network environment, you can only put the test tools and services on the same PC. and the number of connections tested dropped to 2000 The test results r

Curl-loader Introduction Curl-loader (also known as "Omes-nik" and "Davilka") is an open source C language-written tool that simulates the application load and the behavior of thousands of hundreds of thousands of of people's Http/https and FTP/FTPS client applications, Each has its own source IP address. Instead, other Curl-loader use real C-written client-side protocol stacks, the Libcurl and Tls/openssl SSL http and FTP stack, which support the

tools are often developed for a specific purpose, so it's a bit grudging to find an open source performance test tool to compare with LoadRunner or qaload. But open source tools also have their advantages: small, lightweight, offering excellent solutions in areas that are good for you. Therefore, we can consider preparing a "open Source Test Toolbox", peacetime

Summary: There are two main ideas to improve front-end performance: 1>. Reduce the time required for page loading. 2>. Improve the user's perception and make the user feel that the page is faster. To reduce the time required for page loading, you can start with the number of requests, request concurrency, and network transmission time, the page is displayed as soon as possible.
