[ibex-harness-benchmark]

IBEX Benchmark Bot

What and Why

Automated publish of public benchmark history for ibex-harness. Suites in this PR: Proxy, Memory HNSW, Ranking quality, Write pipeline.

Keeps /benchmarks and /benchmarks/memory history current without contributor-authored commits.

Tracking issue

N/A (GitHub App data publish)

How

Proxy suite

Status: ✅ PASS

Field	Value
Run number	886
Head SHA	078d837
Proxy p99 (k6)	1.31 ms
Proxy overhead (Go)	137.69 µs/op
Paths	web/public/benchmarks/benchmark-data.json, web/public/benchmarks/badge.svg

k6 p99 is the authoritative SLA metric. Stage breakdown and ns/op values are synthetic Go microbenchmarks.

• Harness Benchmarks workflow run

Memory HNSW suite

Field	Value
Run number	166
Head SHA	9dcefa8
Mean recall@10	1.0000
Path	web/public/benchmarks/hnsw-benchmark-data.json

Corpus cells

Size	Recall@10	p95	ef	min_sim	iterative	build
10000	1.0000	5.7ms	40	0.70	off	bulk
100000	1.0000	8.8ms	40	0.70	off	bulk

Production-like knobs expected (ef_search=40, min_similarity≈0.70, iterative_scan=off, bulk index build).

Ranking-quality suite

Field	Value
Run number	166
Head SHA	9dcefa8
Precision@5	1.0000
Recall@10	1.0000
Path	web/public/benchmarks/ranking-quality-benchmark-data.json

• Harness Memory Benchmarks workflow run

Write-pipeline suite

Field	Value
Run number	166
Head SHA	9dcefa8

SLA: p95 <= 200 ms.

• Harness Memory Benchmarks workflow run

Testing

• Bot workflow validation passed (suite(s) above)
• Harness CI green on this PR
• /benchmarks and/or /benchmarks/memory preview updated

Performance

No runtime change — history JSON / badge only. Review suite tables above for SLA deltas.

Security

No secrets; App-signed commits; artifacts re-verified via Actions API before publish.

Migrations / Ops

None.

Docs

Public benchmark history only (web/public/benchmarks/*). Suite JSON files stay separate.

Checklist (Definition of Done)

• Correct files only (proxy JSON+badge and/or suite JSON files)
• Labels match files (benchmark-data, hnsw-benchmark-data, ranking-quality-benchmark-data, write-pipeline-benchmark-data)
• Single shared data PR branch chore/bench-data-publish

✅ All benchmarks passed

TL;DR: All collected suites passed. Proxy P99 vs baseline: 📉 -93.9%.

Suite matrix

Suite	Primary SLA	vs Baseline	Status
Proxy	1.22 ms (P99)	📉 -93.9%	✅ PASS

Deep Dive: Proxy

Load test (k6)

• P99: 1.22 ms (SLA < 20 ms)
• Throughput: 1.4k req/s
• Error rate: 0.00%

Synthetic overhead (Go)

• Total: 257.02 µs/op
• Stages: Auth LRU 0.38 µs · gRPC 0.16 µs · Rate limit 0.17 ms · Directive 0.08 ms · Prompt 47 ns

k6 P99 is the SLA. Stage / ns/op values are synthetic Go microbenchmarks, not live traces.

Environment & meta

• Runner: Linux (2 vCPU, 7GB RAM) · Go: 1.25.13 · k6: 0.53.0
• Baseline: 48ea560b8e757aa7114a84c103dacdbef8ee8d34
