linux available memory

Linux memory basic knowledge and related tuning solutions, linux TuningMemory is one of the important components in the computer and serves as a bridge to communicate with the CPU. All programs in the computer run in the memory, so the memory

often encounter some new Linux novice will ask how much memory consumption? In Linux often found that the free memory is very small, it seems that all the memory is occupied by the system, the surface of the memory is not enough to use, it is not.

In Linux often found that there is little free memory, it seems that all the memory is occupied by the system, the surface is not enough memory, it is not. This is a good feature of Linux memory management, the main feature is that no matter how

first, about the computer CPU , Cache , memory, hard disk relationships and differences. 1, the CPU is also called the Central processor (cpu,central processing Unit) is an ultra-large-scale integrated circuit,is the computing core (core) and

I have seen an introduction to the memory pool technology, which has benefited a lot. Original post address: http://www.ibm.com/developerworks/cn/linux/l-cn-ppp/index6.html  6.1 Principle of Performance Optimization for custom memory pools As

It introduces the mechanism of virtual memory and the implementation of MMAP system call. MMAP allows the device memory to be mapped directly to the address space of the user process. The management of physical memory, including cache allocation and

SQLite uses dynamic memory allocations to obtain the memory needed for various objects, such as database connections and SQL preprocessing statements, to establish the memory cache for database files, and to save query results. We've done a lot of

  Understanding the memory model used by Linux is the first step to master the Linux design and implementation to a greater extent. Therefore, this article will outline the Linux memory model and management. Linux uses a monolithic, which defines a
