After reading UNIX file systems, I got to be a bit of a file system junkie. The book does a good job of covering file system design, the block I/O interfaces, caching, the VFS and VNODE abstractions, and the implementation of FFS, VxFS and EXT3. The book piqued my interest in file systems, so I started doing some research on intelligent I/O schedulers and prefetch algorithms. Performing this research has helped me on numerous occassions with understand how to tailor workloads for a given file system and storage subsystem. Since intelligent prefetch is crucial for getting optimum read performance from a file system, and the name prefetch sounded kinda nifty, I decided to register a domain named prefetch.net. Viva la fetch o’ pre!
