WCA 3x3 Fewest Moves statistics with the Julia reference implementation in
WCAStats.jl.
A Rust port lives under rust-wca-stats/ and a C++23 port
under cpp-wca-stats/; both produce value-equivalent CSV
outputs. The current Julia rewrite runs a full WCA export in about 48 s
(vs. ~9.0 s for Rust and ~7.7 s for C++23). See the port READMEs for
usage, source layout and parity notes.
The Julia rewrite and its parity/performance notes are documented in
JULIA_REWRITE.md. Historical profiling notes for the
pre-rewrite DataFrames-based Julia implementation are kept in
PROFILE.md.
Pipeline / cache / memory analysis of the two ports is in
PERF_ANALYSIS.md and can be regenerated on any machine
with perf_topdown.sh.
