SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve? Engineering teams upgrading to Codex-flow v3 need to verify that aggressive performance targets—2.49x-7.47x Flash Attention speedup, 150x-12,500x search improvement, and 50-75% memory reduction—are actually achieved, and detect regressions before they reach production. ## Core Features & Use Cases - Comprehensive Benchmark Suites: TypeScript benchmark classes for startup time, vector search, memory usage, Flash Attention, SONA adaptation, and 15-agent swarm coordination. - Target Validation Gates: Automated validation framework that checks each metric against its target range and reports pass/fail with recommendations. - Continuous Regression Detection: Compares current benchmark runs against baselines and flags regressions exceeding a 5% threshold with severity classification. - Use Case: After integrating AgentDB HNSW indexing, run the memory benchmark suite to confirm search latency improved by at least 150x and memory usage dropped by 50% before merging. ## Quick Start Run the full v3 benchmark suite to validate Flash Attention, search, and memory targets against the performance gates.

FAQPage Schema
How do I benchmark Flash Attention speedup in Codex-flow v3?▼

Use the AttentionBenchmarks class to run standard and Flash Attention over sequences of 512 to 4096 tokens. It computes speedup and memory reduction per sequence length and checks results against the 2.49x-7.47x target range.

How to validate HNSW search performance improvements?▼

The MemoryBenchmarks class times baseline linear search against AgentDB HNSW search over 10,000 generated queries. It reports the improvement ratio and confirms whether it meets the 150x-12,500x target range.

What performance targets does Codex-flow v3 define?▼

Targets include 2.49x-7.47x Flash Attention speedup, 150x-12,500x search improvement, 50-75% memory reduction, under 500ms cold start, under 0.05ms SONA adaptation, and efficient 15-agent swarm coordination.

How does performance regression detection work?▼

The PerformanceRegression class runs the full benchmark suite and compares each metric against a stored baseline. Any metric degrading by more than 5% is flagged with severity classification and recommended fixes.

When should I not rely on these benchmark targets?▼

These targets are specific to Codex-flow v3 internals like AgentDB and SONA, so they do not generalize to other frameworks. Results also depend on hardware, dataset size, and sequence lengths used during benchmarking.
