Algorithm Benchmarks

In version 2.2, with the implementation of the blake3 algorithm, several algorithms were benchmarked:

Dataset: Total of 4161 image files, 10KB to 4MB per file and 609MB total

System: linux (ramdisk)

Command:

hyperfine --export-markdown ../result.md --runs 20 \
--prepare 'fuzzy_rename.py -i .' 'rename.py -i . -H md5' \
--prepare 'fuzzy_rename.py -i .' 'rename.py -i . -H blake3' \
--prepare 'fuzzy_rename.py -i .' 'rename.py -i . -H sha1' \
--prepare 'fuzzy_rename.py -i .' 'rename.py -i . -H sha224' \
--prepare 'fuzzy_rename.py -i .' 'rename.py -i . -H sha256' \
--prepare 'fuzzy_rename.py -i .' 'rename.py -i . -H sha384' \
--prepare 'fuzzy_rename.py -i .' 'rename.py -i . -H sha512'

TODO

  • Benchmark on windows
  • Use normal file system
  • Try on a bigger dataset
  • Merge fuzzy_rename.py with rename.py
