lzbench run, 2026-11-09

mzstd 0.2.12 and the previous release, 0.2.11, against zstd 1.5.7, measured with the lzbench in-memory benchmark on the Silesia corpus. The README’s lzbench table is taken from the 0.2.12 rounds.

Environment

  • lzbench master at a6fa8aa (2026-11-07), reporting itself as lzbench 2.4.1. It vendors zstd 1.5.7 and mzstd 0.2.11. For the 0.2.12 build, its lz+entropy/mzstd directory was replaced by this release’s sources; lzbench still labels the codec “mzstd 0.2.11”, the version its codec table names, so the 0.2.12 output below is relabelled.
  • gcc 15.2.0, rustc 1.99.1. Built with make BUILD_ONLY='ZSTD MZSTD' MOREFLAGS="-march=native"; the Rust codecs use lzbench’s default RUST_TARGET_CPU=native, so both sides target the same CPU.
  • AMD Ryzen 9 7950X VDS (2 vCPU, KVM), Linux 7.0, default CPU governor and boost. The host is shared with other tenants, who loaded it throughout the day: a fixed C decode varied by 8-43% between its 10th and 90th percentile wall times. The benchmark is pinned to one vCPU with taskset -c 1.
  • Input: silesia.tar, 211,957,760 bytes, the twelve Silesia files in a ustar archive, compressed as one stream.

Command

taskset -c 1 ./lzbench -t8,8 -o1 \
  -ezstd_fast,-5/mzstd_fast,-5/zstd_fast,-3/mzstd_fast,-3/zstd_fast,-1/mzstd_fast,-1/zstd,1/mzstd,1/zstd,2/mzstd,2/zstd,3/mzstd,3/zstd,5/mzstd,5/zstd,8/mzstd,8/zstd,11/mzstd,11/zstd,15/mzstd,15/zstd,18/mzstd,18/zstd,22/mzstd,22 \
  silesia.tar

-t8,8 repeats each compression and decompression for at least eight seconds and reports the fastest iteration. Codecs are interleaved level by level so that drift on the shared host affects both sides of a pair alike. Because the host was loaded, the command ran in three rounds, each the 0.2.12 build followed by the 0.2.11 build (14:45 to 15:08 UTC, then 17:27 to 18:13 UTC). The tables below take, for every codec and level, the fastest result of the three rounds, extending lzbench’s own fastest-iteration rule; the raw output of every round is at the end.

Speed relative to zstd

Each value is mzstd’s speed divided by zstd’s, both the fastest of the three rounds; the rounds columns give the ratio within each round. The two releases are compared through the zstd beside them rather than through absolute speeds. Compressed sizes are byte-for-byte equal at every level in every round.

Decompression ratios reproduce within about 2% between rounds, except at level 22 (0.921 to 0.998), and so does compression at the --fast levels and level 1. Compression at level 2 and above moves by 3% to 21% between rounds (level 8: 0.848 to 1.030) on this host, so differences of a few percent there are within noise. Against 0.2.11, decompression is faster relative to zstd at levels 1 to 22 (level 1: 0.883 to 0.933, level 2: 0.906 to 0.933) and level 3 compresses at about zstd’s speed (1.011) instead of 0.973 of it, from the branchy candidate tests of dfast.
