sap performance testing

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,

The concept of performance testing is what, the basic purpose is what, I think everyone is basically clear, not to be detailed, in short, performance testing is just one way in the test process, to help our function better run, if the functional test is available, easy to use, to meet the needs, users for purposes,

The skills that testers should have: 1, master the common use of automated testing tools; 2, with a certain degree of programming ability; 3, master the basic knowledge of the database; 4, master the common operating system knowledge; 5, master the use of some Web application servers, such as: Weblogic, Webshpere; 6, has the comprehensive analysis question ability; Performance Test Terminology: 1, c

What is the concept and basic purpose of Performance Testing? I think everyone knows it clearly and I will not elaborate on it. In short, performance testing is only a method in the testing process, it helps us to run our functions better. If function

Efficiency compliance: Software products follow the standards or conventions associated with efficiency.Software performance is an indicator, is a non-functional feature of software, it is not concerned about whether the software can complete a specific function, but the response of the function of timeliness. Performance is

Performance counters (counter) are some data metrics that describe the performance of a server or operating system. Counter plays a key role in performance testing, especially in analyzing the scalability of the system and locating the performance bottleneck, the analysis of

Throughout the performance testing process, monitoring plays a vital role. After the performance test starts, you need to observe in real time whether all the indicators of the performance test are normal, including application servers, databases, and middleware. Once exceptions are detected, the system can be correcte
