sap performance testing

A problem during performance testing is the time interval. Many time functions can obtain the time to obtain the time interval. I will not repeat many articles in this regard. Here I only provide some basic information to facilitate my own performance testing: (1) c language time functions clock () and clock_t: The C l

PS: In operation and maintenance work, stress testing is a very important work. For example, before a website online, can withstand how much traffic, in the case of large traffic performance, these data indicators will directly affect the user experience. However, in the stress test there is a common denominator, that is, the results of the stress test and the actual load results will not be identical, even

Some time ago, in Ali mother new room pressure test process used in the LR test Oracle, with the DBA (landlords) in Hangzhou netcom New computer room for 1000 users of the pressure simulation test. The entire stress test takes two days. The following are some of the experiences: 1 The stress test process found that some of the SQL scripts performed very slowly and were optimized. 2 The best concurrent testing, otherwise the service is basically no p

Recently, sysbench has been used for many performance tests. It also summarizes its features and usage and precautions. Sysbench is a multi-thread performance testing tool that can perform performance tests such as CPU, memory, IO, and database. However, most of the time I use it to perform oltp tests on databases (MyS

There are a lot of performance tools on the Linux platform, a dazzling, long-term groping and experience finding the best thing to use is the proven, simple gadgets. Brendan D. Gregg, a system performance expert, updated his famous talk (Linux performance Tools) and slides on Linux in the recent LinuxCon NA 2014 conference.Compared with Brendan last year's talk,

P-Unit-unit-level open-source performance testing framework Http://p-unit.sourceforge.net/ An open source framework for unit test and performance benchmark, which was initiated by Andrew Zhang, under Apache license v2.0. P-Unit supports to run the same tests with single thread or multi-threads, tracks memory and time consumption, and generates the result in t

The Uptime command of the Linux performance testing tool displays how long the server has been running, how many login users there are, and the overall load average evaluation of server performance ). The load average value records the number of processes waiting for execution in the queue for the last 1 minute, 5 minutes, and 15 minutes respectively ). The main

A document prepared last year has recently been used for performance tests. I have provided a reference and shared it with you. Pai_^ If you think of more items, you can leave a message for discussion. 1. Have developers submitted a test application? 2. Are the test objects specified? 3. Is the test Scope clear? 4. Is the scope of this test not to be tested clear? 5. Are the test targets clear? 6. When will

smallest unit of the transaction that the Web app can handle. If you define each click as a trade, CTR and TPS are a concept. It is easy to see that the greater the CTR, the greater the pressure on the server. CTR is just a performance reference, and it's important to analyze the impact of clicks. Note that the Click here does not refer to a single click of the mouse. Because in a single click, the client may make multiple HTTP requests to the server

1, why pay attention to performance issues?Now the app is in a " bonus period ", want to fightout from, is simply the Arabian Nights. So not successful breakout, where are the problems and bottlenecks? Most developers will be due to the product design, product logic and other closely related links, but will ignore a blind spot, is the performance problem. You've seen a set of stats before:· 71% users want t
