Razvan Dimescu	f8e340ca17	chore: simplify benchmark code after review ... - Remove redundant DnsHeader::new() (already set by DnsPacket::new()) - Remove unused DnsHeader import - Change simulate_cached_pipeline to take &DnsCache (lookup is &self now) - Remove unnecessary mut on cache in cache_lookup_miss bench Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>	2026-03-25 06:14:00 +02:00
Razvan Dimescu	aed0e095e1	perf: optimize hot path — RwLock, inline filtering, pre-allocated strings ... - Mutex → RwLock for cache, blocklist, and overrides (concurrent read access) - Make cache.lookup() and overrides.lookup() take &self (read-only) - Eliminate 3 Vec allocations per DnsPacket::write() via inline filtering - Pre-allocate domain strings with capacity 64 in parse path - Add criterion micro-benchmarks (hot_path + throughput) - Add bench README documenting both benchmark suites Measured improvement: ~14% faster parsing, ~9% pipeline throughput, round-trip cached 733ns → 698ns (~2.3M queries/sec).
