Decoder comparison

Benchmark index

Recorded run: long-20261109 (2026-11-09). CSV · Environment · Methodology and limits.

Each value is the median of C mean time / decoder mean time across all 8 datasets, equally weighted. Higher is faster; 1× matches C. Levels are ordered by mzstd median speed / C. Medians do not imply statistical significance.

Both decoders restore identical C-written frames. The level is an encoder setting, not a decoder setting. Compressed sizes and ratios are properties of those shared inputs, so there is no decoder size ranking.

Open a source level for all datasets, compressed/restored byte counts, mean latency, confidence bounds and throughput. Measurements include cold construction, allocation, decoding and disposal. C receives the frame’s declared output capacity. See the linked methodology for reproducible commands and the limits of this single-host comparison.
