Tuning Disk and File System Performance
Almost every task performed by Unix relies on the file system in some way, whether it is executing a program or querying a database. Due to its heavy use of file system data, properly tuned file systems and disks can often have a far greater impact on overall system performance than any amount of CPU tuning. This section discusses some of the most effective methods for tuning disks and file systems, including
Using disks with high rotational speeds
Proper placement of file systems on disk
Using RAID-0 (striping)
Optimizing the number of inodes in a file system
Using Disks with High Rotational Speed
The simplest way to get top disk performance is to use disks with high rotational speed. The rate at which a ...
