Optimizing MySQL at compile timeIf you install MySQL from the source code, note that the compilation process will have an important impact on the performance of future target programs, different compilation methods may get similar target files, but performance may vary greatly, therefore, in the compilation and installation of MySQL adapt carefully according to your application type choose the most likely good compilation options. This custom MySQL can provide the best performance for your appli

. From the outward appearance, the difference between them is mainly the length and the number of pins, as well as the corresponding gap on the pin. FPM Ram was popular in the 286, 386 era, when it used 30pin FPM RAM memory with a capacity of only 1MB or 2MB. And in the 486 era, and a few 586 computers also use 72pin of FPM RAM memory. EDO RAM is mainly used in 486, 586 times, also has 72pin and 168pin points. In terms of appearance, 30pin of FPM RAM memory is the shortest, 72pin FPM RAM and

Timers can be used as program components to help programmers precisely control program processes, and are also a powerful debugging weapon. experienced programmers can determine program performance bottlenecks as soon as possible, or for different Algorithm Make a convincing performance comparison.On Windows, there are two commonly used Timers: timegettime multimedia timer, which provides millisecond-level timer. However, this accuracy is still too rough for many applicatio

This chapter is selected from the Intel official documentation and translated by myself. Note that the following English word cache is used. If C is in uppercase, that is, cache, it indicates the term "cache". If C is in lowercase, that is, cache, indicates the verb -- indicates saving data to a high-speed buffer storage. Intel 64 and the IA-32 architecture provide the ability to manage and enhance the execution of multiple processors connected to the same system bus. These include:

(for example, using an array of known spans), they are good candidates for using prefetch to improve performance. Use the prefetch command in the following format: ● Predictable Memory Access Mode ● The most time-consuming cycle ● The execution pipeline may be delayed. If the data is unavailable 7.4.2 prefetch command-Implementation of the Pentium 4 processor The stream SIMD extension contains four variants of the prefetch command, one non-temporary

memory frequency. The CPU uses this frequency to contact the memory. The CPU clock speed is the actual operation speed inside the CPU. The clock speed must be a factor higher than the external frequency, which is a multiplier. For example, you have picked up an Intel 486 CPU from the computer garbage collection, with 486 dx/2 66 printed on it. The 486 CPU clock speed is 66 MHz, and dx/2 represents a 2-frequency doubling. Therefore, the outbound CPU frequency is 33mz, that is, the memory operati

The flag is ignored for privileged level 0, 1, and 2. VIF (virtual interrupt flag) indicates the virtual interrupt flag. The following three marks are available for CPUs after Pentium. When VIF is set to 1, virtual interrupt can be used. When VIF is set to 0, virtual interrupt can
