Linux Command Memory Size

I. Introduction We often see some similar in the program disassembled code 0 × 32118965 this address, the operating system called linear address, or virtual address. What is the use of virtual address? Virtual address is how to translate into physical memory address? This chapter will give a brief account of this. 1.1 Linux Memory Addressing Overview Modern operating systems are in 32-bit protected mode. Each process can generally address 4G of physical space. But our physical memory is generally hundreds of M, the process can get 4 ...

This usage is very practical for the following applications: write-intensive cache embedded systems that precede a slow RDBMS system require a lightweight database and a unit test that data in the library can easily be purged without the need for a persistent data-compliant PCI system (testing) If all this could be done, it would be elegant: we would be able to manipulate http://www.aliyun.com/zixun/aggregati without involving disk operations ...

The Linux system provides us with the solution, that is, the Tmpfs file system, TMPFS can use the memory directly, while not enough memory to use the swap partition to store. Also note that TMPFS is not persistent, restart data does not retain, please be sure to note, but we only use it to store cached files, even if the file is lost does not affect the site access, there is no risk. /dev/shm/is a device file that uses the Tmpfs file system (note: Under CentOS and Redhat,/dev/...)
