Greptile Summary

Updated build performance benchmarks for v2.4.0, reflecting the addition of native complexity analysis across all languages.

• Build times increased from 2.1 ms/file to 6.7 ms/file (native) due to new complexity analysis feature
• New "Build Phase Breakdown" section shows complexity analysis accounts for 72% of native build time (588.4ms out of 813ms)
• All metrics accurately calculated and consistent between README.md and generated/BUILD-BENCHMARKS.md
• Added granular query latency metrics (fn-deps, path) and incremental rebuild benchmarks
• File count increased from 109 to 122 as codebase expanded

Confidence Score: 5/5

• Safe to merge - automated benchmark documentation update with accurate metrics
• This is a generated documentation update from CI workflow with verified data accuracy. All calculations are correct, metrics are consistent across files, and the changes properly document expected performance trade-offs from the new complexity analysis feature introduced in PR perf: native complexity for all languages + phase benchmarks #149.
• No files require special attention

Important Files Changed
