I. File Read speed In Linux, reading files is implemented by calling sys_read (FD, Buf, count) by the system. Therefore, to increase the speed, it is the simplest way to call the sys_read encapsulation, for example, read () or fread () is used directly (). Below are some tests in Linux. First create a 130m data file dd If =/dev/Zero of = data BS = 1024 k count = 130 [Dd If =/dev/Zero of = data BS = 1024 k c

Test and analyze the speed of PHP core functions for data extraction. Test and analysis on the speed of the core function for extracting PHP Data, and test the execution speed of the core part of the character extraction in PHP co

Time is used for timing. dd is used for copying, reading from if, and writing to. If =/dev/zero does not produce IO, so it can be used to test the pure write speed. Similarly, of =/dev/null does not generate IO and can be used to test the pure read speed. Bs indicates the size of each read or write, that is, the size o

Time has a timing effect, DD is used for copying, reading from If, and writing to. If=/dev/zero does not produce IO, so it can be used to test pure write speed. Similarly of=/dev/null does not produce IO, which can be used to test the pure read speed. BS is the size of each read or write, that is, the size of a block,

Test on slow table data deletion: recently, I was bored with my watch and found that data deletion is far from faster than query. As a result, I made an experiment. The experiment content is as follows, and the level is limited. I hope it will serve as an example to help you understand this problem as much as possible! I hope that our predecessors can clearly and relentlessly correct the unreasonable operations and incorrect ideas of our younger sibli
