Host: x64 build worker; AMD Ryzen 9 7950X3D 16-Core Processor; 32 logical cores; Linux Mint 22.3 X64
ISA: sse4.2 avx2 bmi2 avx512f avx512bw
Storage of the corpus: /dev/nvme0n1p4; every file is read once before its rows, so it is in the page cache for all of them
.NET: 10.0.13 (.NET 10.0.13)
Load average (1 min): before 9.62; during mean 5.12, max 9.62 over 32 samples at 5 s; after 2.83
Elapsed: 2.7 min; repetitions 5 (managed), 3 (tools); files over 1 GiB get one warm-up run and 3 samples of one run each, and tools once
Packages as restored: SharpMP4 0.3.2; RecursiveAI.OneAudio 1.4.0; MetadataExtractor 2.9.3; TagLibSharp 2.3.0.0; z440.atl.core 7.19; Matroska 0.0.12

Ratio is OneMedia's median over the fastest managed comparator's median on the same file (below 1.00× is faster). Peak is the process's peak resident set; Baseline is its resident set before any work, so Peak − Baseline is what the work added.
