Some experiments on deduplicating contents at sub-file granularity using Rabin fingerprints.
Linux kernel, Git repo
- origin: git.kernel.org, on 2018-01-06
- 1.653.941 content blobs, for a total of 19 GB (compressed)
test 1
Rabin fingerprint parameters:
- prime: 3
- window_size: 48 KB
- min_block_size: 2 KB
- avg_block_size: 8 KB
- max_block_size: 64 KB
Results:
- original size (uncompressed): 55.89 GB
- dedup chunk size (uncompressed): 19.87 GB (35.55%)
