First, a simple test of the CPU:1. Calculate special functions by BC commandExample: Calculating piecho "scale=5000; 4*a (1) "| Bc-l-Q MATH LIBRARYIf BC is invoked with THE-L option, a math library is preloaded and the default scale is set to 20.The math functions would calculate their results to the scale set at the time of the their call. The MathLibrary defines the following functions:S (x) the sin

Article title: comprehensively analyzes the stress test on Linux kernel. Linux is a technology channel of the IT lab in China. Includes basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open source. Automated Software Testing allows you to run the same test within a period of time to ensure that the con

Web development, it is the stress test, it is to assess whether a product is eligible to go live on the basic standards, let us analyze how they use.Before the test, the number of ports in front of the system is changed to large, look at the default limits of the Mac ulimit -aopen files (-n) 2560 More tha

Problems in the stress testWhat is a stress testSoftware stress testing is a basic quality assurance behavior that is part of every important software testing effort. The basic idea of software stress testing is simple: not to run manual or automated tests under normal conditions, but to run tests with fewer computers

SummaryAfter we have set the parameters as above, we have carried on the concurrency test of the application (the test machine and the same intranet segment of the server were kept in the test), and for the first time we simulated 100 user concurrent requests (the request needs to be queriedA data table with 1000 data is execute

These systems cover a wide range of functions such as product promotion, merchandising, transaction settlement, service and customer feedback. When it is necessary to pro

求的响应情况. Each request in the scene has a response time, where 50% of the user's response time is less than 275 milliseconds, 66% of the user response time is less than 298 milliseconds, and the maximum response time is less than 11843 milliseconds. In the case of concurrent requests, the CPU is not actually processed at the same time, but is rotated on a per-request basis, so basically the first time of the request is approximately equal to the second

The full name of AB is apachemeter, which is an Apache network stress testing tool. compared with LR and JMeter, AB is the simplest and most common Http stress testing tool I know. The AB Command has very low requirements on the computer that sends out the load and does not occupy high CPU and memory. However, it can also generate huge loads on the target server

.html A simple explanation: the server with too many concurrent access requests rejects access. Theoretically, the system configuration can provide better affordability. ⑤. Precautions Test Machines and tested machines should be separated Do not perform stress tests on online servers Observe that the machine where the test tool AB is located and the
