Benchmarking and + comparing DwarFS

+

DwarFS is a filesystem developed by the user mhx on GitHub + [1], which is self-described as "A fast high compression + read-only file system for Linux, Windows, and macOS." One of my + ideas for blendOS was to layer different packages, and combined + with its compression and option to be mounted as a FUSE-based + filesystem, it's an appealing option for this use case - blendOS + is immutable, so it might as well have some compression.

+

Methodology

+

The datasets being used for this test will be the + following:

+ +

All this data should cover both latency and read speed + testing for data that compresses differently - extremely + compressible files with null data, decently compressible files, + and random data which can't be compressed well.
