database update 10,000 records when the consumption of "onlyorm" test results: 13711.9439 ms22, let the database delete 10,000 records when the consumption of "onlyorm" test results: 17200.4408 ms From the above results can be seen: onlyorm efficiency is significantly lower than the Maincache+daemonorm way, of course, if not enable transactions should improve efficiency, but in the production environment I adopt the Maincache+daemonorm way,because it is very efficient, of course, the legend cl

The storage process from Julian Dyke to test the single-core CPU performance can test the single-core CPU processing capability. By the way, I also tested SET SERVEROUTPUT ONSET TIMING ON DECLARE N NUMBER: = 0; BEGIN FOR f IN 1 .. 10000000 LOOP N: = MOD (n, 999999) + SQRT (f ); End loop; DBMS_OUTPUT.PUT_LINE ('res = '| TO_CHAR (n, '192. 99 ')); END; / The following is an output sample: SQL>/ Res = 873729.72 PL/SQL procedure successfully completed.

For reference only) Test results: I tested several types of CPUs, and it turned out that one of my testing machines (Intel CPU) was the fastest, killing HP and IBM in seconds. Of course, the single-core processing capability is only one aspect, stability and concurrency are the secrets of small machines HPUX anteng PlatformElapsed

1. A/B testing some terms related to grayscale publishing Test Origin 1.1 barrels test (bucket testing): This is not a clear definition, but it is usually a comparative test abroad for testing the pool for leaks.

Performance testing (or multiprocessing user concurrency performance testing), load testing, strength testing, and capacity testing are some of the areas of performance testing, but concepts can be easily confused.

1. The question was raisedSelf-test during product development is an important part of ensuring product quality, and automatic testing is one of the effective ways to improve product quality and improve research and development efficiency.The factors to consider when designing automated tests include the following:First, the adequacy of the test case.Second, code coverage is as high as possible.Thirdly, a r

You can use the development and testing environment for one dollar to quickly create a Halloween promotion application. As a dedicated employee, I love many holidays, such as spring festival, Labor Day, and National Day. I hate many holidays, such: valentine's Day, Teacher's Day, and Halloween (do not have a holiday,

01 Half of the product development Some people think this title is a bit ironic, the real test. , aren't we really testing, and the usual thing is not testing work. In fact, not sure, but this is a containment relationship, if only the review + use case writing execution, then really is not

A The concept of software testingTesting involves all aspects of our lives, and it is a very broad concept. The test is with the development of modernizationto produce. Software testing, which is part of software engineering. Test activity is an engineering activity that does notis a simple, isolated activity.1.1What i

I thought that my graduation design was a test-driven development, so I had a deep understanding of unit testing and test-driven development since the beginning, and I have been a loyal fan of agile development at the beginning. However, after several years of work, I began to have

1. What is software testing?Definition of software Testing the teacher gave the following versions.(1) Software testing is designed to evaluate the properties or capabilities of a program or system to determine whether it meets the required results.(2) Software testing is to
