Performance improvements for bFS Carton, Ross W.


The traditional file system was designed on the premise that it would be deployed within a trusted and restricted administrative domain, i.e. the domain was restricted to a set of users managed by a trusted system administrator. The Internet is neither trusted nor restricted, so a file system to be deployed on the Internet challenges the traditional file system model. bFS [8] is a file system model and implementation that addresses the challenges raised by deploying a file system on the Internet. These challenges are very real, as Internet-based storage providers become more prevalent. The original bFS implementation was a completely functional prototype, however it suffered from very poor performance. This thesis describes an improved implementation, and shows that its performance now compares favourably to plain unencrypted NFS.
