FTS Engine (src/barabadb/fts/engine.nim):
- Fix bm25Score doing O(n) linear scan per document
- Cache IDF per token instead of recomputing for each doc
- Use entry.termFreq directly instead of searching postings again
- Result: FTS search +438% (249 -> 1360 queries/s)
HNSW Vector Engine (src/barabadb/vector/engine.nim):
- Optimize distance functions with float32 + 4x loop unrolling
- Rewrite searchLayer: swap+pop instead of O(n) del, track worst-nearest
instead of sorting nearest on every iteration
- Result: HNSW insert +117% (245 -> 543 ops/s), search 2.2x faster
Benchmarks:
- Add real PostgreSQL comparison script (benchmarks/pg_bench.py)
- Add report generator (benchmarks/generate_report.py)
- Fix compare.nim cpuTime() bug (was dividing by 1M incorrectly)
- Add nimble tasks: bench_pg, bench_report
Docs:
- Update README.md and docs/en/performance.md with real measured numbers
- Add benchmarks/REAL_COMPARISON.md
Version bump: 1.1.7 -> 1.1.8
