MySQL database optimization 1.4 MySQL benchmark suite
This chapter would have included the technical description of the MySQL benchmark suite (and crash-me), but it has not yet been written. Now, you can have a better idea by viewing the code and results in the MySQL release source code 'SQL-encoding' directory.
The benchmark suite is to tell the user what kind

How can I find out the performance of a Linux PC?GuideA benchmark is a test or a series of tests used to determine how well a computer's hardware is running. In many cases, "Benchmarking" is actually equivalent to "stress testing ". By testing the hardware limits, we can then compare the measured results with those measured by other hardware.
Most benchmarking tests are intended to simulate the workload that PCs encounter in actual situations. Becaus

With regard to PhP, many people intuitively feel that PHP is a flexible scripting language with rich library classes, simple to use, and secure. It is very suitable for web development, but its performance is low. Is PHP performance really as bad as everyone feels? This article focuses on this topic. In-depth analysis of PHP performance problems from the source code, application scenarios, benchmark performance, comparative analysis, and othe

Benchmark Testing errors:
Use a subset of real data instead of a complete set.
Does not match real user behavior.
No check error. ----------- Check the error log when unexpected results are encountered during the test. The basic requirements are as follows.
Ignore the system warm-up process-after the system is restarted, there is no data in the cache. In this case, the test is not in line with the actual situation. In fact, it is likely that the

One of my cousins was an engineer. I had an apprenticeship in the factory in my early years. Later I went to college and got a master's degree. I had a solid theoretical and practical skills. Once, he asked me a question: how is the tablet used by the fitter?. The fitter's plate is actually a hard iron plate with a very smooth surface that can reach a flatness of less than 1mm. The fitter uses the plate as the
