Veritas File System provides a set of tuning options to optimize file system performance for different application workloads. VxFS provides a set of tunable I/O parameters that control some of its behavior. These I/O parameters help the file system adjust to striped or RAID-5 volumes that could yield performance far superior to a single disk. Typically, data streaming applications that access large files see the largest benefit from tuning the file system.

Most of these tuning options have little or no impact on database performance when using Quick I/O. However, you can gather file system performance data when using Quick I/O, and use this information to adjust the system configuration to make the most efficient use of system resources.
