not yet reacted, and looked at the old farmer dashed, jumped to the back of the Mule (which is equivalent to the limit of the capacity test), the poor mule, in any case, will not think that this hard-hearted farmer after it has been gone for so long, not only did not help it to remove the burden of the body, but also did not give it to drink saliva, Unexpectedly jumped to its already curved back. Poor mule, it's just such a life! I saw the mule, the

time is directly manipulating the data in memory, is not CPU performance bottlenecks, it is necessary to look at the CPU usage and queue length. If CPU usage is high, CPU bottleneck, CPU usage is not high, queue is very long, CPU is blocked, need detailed analysis reason (back up analysis). CPU usage is low and queues are not long. Non-CPU bottleneck Memory: High usage bottleneck, not high non bottleneck. Nothing to say. Disk: Disk is much slower th

A long time ago said to sum up his career, has been busy with some of the mess, now rare to steal idle, take advantage of the feeling, hurriedly knocked down "These years, my software performance Test " To honor my this IT industry for a few years ...Remember the first time to do the performance

Once testing the performance of the distributed cluster system under the Linux system, using some test software, the company let me give the department colleague to do a basic training, and then look at the previous written records selected a few of them, the memory is not complete, only record the use of functions.1.IozoneIOzone is a file system benchmark tool t

We all know Zend Optimizer This tool is Zend provides a free PHP acceleration software, the official said that this tool can make PHP performance improvement of 30%-40%, I recently personally tried, the Zend optimizer specifically done a test, Discovery can actually improve PHP efficiency. Here is the whole process of testing. The PHP script used in the

Analysis principle:Specific issues specific analysis (this is due to different application systems, different test purposes, different performance concerns) Find bottlenecks in the following order, from easy to difficult. Server hardware bottleneck-〉 network bottleneck (for LAN, can not be considered)-〉 server operating system bottleneck (parameter configuration)-〉 middleware bottleneck (parameter configura

passed function, then call the measured function inside the function, then test the result, such function is called the driving function.5. Black box test and white box test what is the difference black box testing does not take into account the internal logic structure and characteristics of the program, through the exhaustive input

Performance testing, load testing, stress testing What's the difference? Performance testing (or antisymmetric user concurrency performance testing), load testing, strength testing, and capacity testing are some of the areas of performance testing, but concepts can easily be confused. Here are a few concepts to introdu

projects. PC-Lint can help you find coding errors before dynamic testing of the program and reduce the cost of eliminating software errors. With PC-lint, you can check code before code reading and unit testing. You can detect program hidden errors in advance, improve code quality, and save test time. In addition, the

operation. Depending on the time and resource characteristics of the product, the efficiency test can include different types of tests, such as performance tests (performance test), load tests (loading test), and stress tests (Stress te
