This article mainly shows you the "sample analysis of Linux installation performance", which is easy to understand and well-organized. I hope it can help you solve your doubts. Let the editor lead you to study and study the "sample analysis of Linux installation performance".

Before installing a Linux system on a hardware system, you need to consider a number of performance issues that help optimize the operating system and the applications that run on it in the future. These questions include:

Select Partition location

Use multiple hard drives

Select a file system

Linux requires at least one root partition and one swap partition, and the location of these two partitions and other frequently accessed partitions on disk will eventually affect the performance of the system.

For var, swap, / var, / usr, and / home partitions, separate partitions are used

The disks of most hard drives encapsulate more sectors on the outside track than on the inside track, so it is much faster to read data from the outside track. Lower-numbered partitions are usually installed on the external track (for example, / dev/hda1 is closer to the outer edge of the hard drive than / dev/hda3), so place the partition that needs to be accessed frequently first

* partitions should be swap partitions (used to optimize memory swapping operations)

The second partition should be / var because log records are frequently written to / var/log

The next partition should be / usr, because the basic system tools and commands are located in / usr

Root and / home partitions can reside near the end of the hard drive

Use multiple hard drives and make full use of multiple hard drives.

Install frequently accessed partitions to a faster hard drive

If the performance of these hard drives is similar, install the commonly used partitions on different hard drives. For example, / var and / usr partitions are placed on two different hard drives, while swap partitions are on their own separate hard drives

For * bus throughput, each hard drive that acts as a master device should be placed on the I _ swap O channel. The device name of a hard drive changes after it is moved between different Ihammer O channels, so the file system table (/ etc/fstab) needs to be changed accordingly. If you move a hard drive that contains root or / boot partitions, you also need to edit the / boot/grub/menu.lst file

File system Typ

An improved version of ext4,ext3, providing more performance and reliability, and richer features

ReiserFS with better performance for small files

XFS with better performance for large files
