in testing is to prepare the (Prepare) phase, generate the data files used for the test, and generate a data file that is at least larger than the memory. If the data in the file can be completely put into memory, the operating system caches most of the data, causing the test results to fail to reflect IO-intensive workloads. First create a DataSet with the following command:Sysbench--test=fileio--file-total-size=40g PrepareThis command creates a tes

Front-end framework sharing Second, in order to learn the object-oriented, we must learn design patterns.Assuming we understand the object-oriented purpose, the concept, but we coding in the process found that our object-oriented knowledge seems to have been useless, in fact, it is very simple, because we do not know how to use, like swimming, we have understood th
it a little further, and let's imagine what happens when the contents of a 10MB sized file are loaded into two variables. This will take up 20MB of space, at which point 10 is enough. Will the engine waste so much time and memory on such a useless endeavor?
You know, PHP's designers have long been familiar with this.
Remember, in the engine, variable names and their values are actually two different concepts. The value itself is an unnamed zval* st

variable is created, and a 12-byte block of memory is assigned to it to store the string "Hello world", including a null character at the end. Now, let's look at the following two lines: The $b is set to the same value as the variable $a, and then the variable $a is released.
If PHP replicates variable content for each variable assignment, the string to be copied in the previous example also requires an additional 12 bytes to be copied and another processor load during data replication. This be
