# Throughput scoreboard

Generated by `python3 harness/scoreboard.py` on 2026-10-17.

- Machine: 12th Gen Intel(R) Core(TM) i5-12500H
- Toolchain: `moon 0.1.20261012 (748b63c 2026-10-12)`
- Method: `harness/bench` (release build) encodes and decodes fixed datasets, warming up once and then running enough iterations to reach roughly 200 ms per phase; MB/s is computed against the PLAIN input size. Numbers are single-machine and not comparable across hosts.
- Ratio is encoded bytes against PLAIN for the same column.
