synchronized or that have different priority levels. through buffers, you can reduce the number of waits between processes, so that when you read data from a slow device, the operating process of a fast device is uninterrupted.Buffer and cache in free: (They are all memory-intensive):Buffer: Memory as buffer cache, which is the read and write buffer of the block

-ef | grep ' process name ' gets the PID of the process. This command can provide information such as the status of the process, the number of file handles, memory usage, and so on.Memory-relatedVmstat-s-S MYou can view the reports that contain each item in memory, and you can specify which units to view by using-S M or-s K, which defaults to KB.

programs running, but using the top or the free command to see the available memory is rare.What is cache memory (cached RAM):When you read and write files, the Linux kernel caches the files in memory for increased read and write

Tags: ext PCA and shmget further software kernel space Write CenterIntroduction: The top command, as one of the most commonly used performance analysis tools under Linux, can monitor and collect CPU, IO, and memory usage of the process. For example, we can use the top command to get how much virtual

), but also adopted two main cache mode: Buffer cache and Page cache. The former is for the disk block read and write, the latter for the file inode read and write. These caches effectively shorten the time for I/O system calls (such as read,write,getdents).How to solve the problem that causes the machine to become slow?The main culprit is that the

Introduction Can you write command line tools? Maybe you can, but can you write a really useful command-line tool? This article discusses the use of Python to create a robust command-line tool with built-in Help menus, error handling, and option handling. For some strange r

The switch statement always has a default branch, and each case has a break, which must be explained. 5. Write as few as possible. It is best to have only one return at the end of the function. 6. brackets are added to each part of the ternary operator. 7 if-Else, the branch in sw

Shell is a program for managing processes and running programs. All common shells have three main functions. (1) run the program Grep, date, ls, ECHO, and mail are common programs written in C and compiled into machine languages. Shell loads them into memory and runs them. Many people regard shell as a program starter. (2) Manage Input and Output Use the (3) Programming Shell is also a programming language with variables and flow control.

In Java programming, you want to know the CPU usage to determine whether to load the task. First, search by google. In Windows, you can use JNI to Use API functions.GetProcessCPUTime (), and someone gives the source code. Linux does not seem to have any source code, so I decided to write it myself. After practice, I finally succeeded. Now I willPost the code and share it with you. The idea is as follows: in Linux, you can use the top

You want to know the CPU usage during Java programming so that you can decide whether to load the task. First with Google search, Windows environment can use JNI through the API function Getprocesscputime () to get, and someone gave the source code. Linux seems to have no one to give the source code, so decided to write one, after practice, and finally succeeded, is to post code, and share with you.Thinking as follows: The Linux system can use the top

Buffer (buffers) is based on the disk read-write design, the decentralized write operations centralized, reduce disk fragmentation and hard disk repeatedly seek, thereby improving system performance.The cache is often used on disk I/O requests, and if more than one process accesses a file, the file is made int
