Disk I/O is one of the most important bottlenecks in the server's performance. Default disk configuration in every operating system is optimally designed to fit the general usage. However, you may need to reconfigure disks for your specific usage, to get the best performance. This includes choosing multiple disks for different partitions, choosing the right partition size for specific usage, and fine-tuning the swap size. This chapter discusses how to use the right partition size and tuning file system to gain better performance on your FreeBSD servers.
In this chapter, we will look into the following:
Partition layout and sizes
Swap, softupdates, and snapshots
File system back up
