The master's thesis deals with a support of caching in GVfs (Gnome Virtual filesystem). Basics of caches, cache invalidation, and cache replacement algorithms are described. Description of GIO filesystem abstraction and communication of modules within GVfs is provided next. The disadvantages of individual GVfs modules and, if present, their internal caches are discussed. The thesis proposes three types of cache. The first type of cache is for storing file metadata, the second one for directory listings, and the latter for file content. These caches have been implemented in a prototype and verified with respect to the functionality and performance. The main benefits of the proposed solution are faster work with virtual filesystems and provided missing functionality of lower-level virtual filesystem to GIO abstraction (namely, for instance seek operation).
