Benchmarks

Benchmarking the performance of

• one px-repack process per DICOM file
• one px-repack process for the entire series (batch mode)

Hyperfine Command

hyperfine --runs 3 --prepare 'rm -rf /tmp/dicom' \
'fd --type f --exec px-repack --xcrdir {//} --xcrfile {/} --verbosity 0 --logdir /tmp/dicom/log --datadir /tmp/dicom/data \; . data' \
'px-repack --xcrdir data/anonymized_20230714_184245695 --parseAllFilesWithSubStr , --verbosity 0 --logdir /tmp/dicom/log --datadir /tmp/dicom/data'

Hyperfine Results

Benchmark 1: fd --type f --exec px-repack --xcrdir {//} --xcrfile {/} --verbosity 0 --logdir /tmp/dicom/log --datadir /tmp/dicom/data \; . data
  Time (mean ± σ):     11.221 s ±  0.103 s    [User: 137.516 s, System: 64.497 s]
  Range (min … max):   11.123 s … 11.328 s    3 runs

Benchmark 2: px-repack --xcrdir data/anonymized_20230714_184245695 --parseAllFilesWithSubStr , --verbosity 0 --logdir /tmp/dicom/log --datadir /tmp/dicom/data
