Benchmark Report — ABS Core Governance Engine
Three-tier performance validation: endurance (200 req/s / 2h), load (1k req/s / 60min), stress (5k req/s / 15min). Results anchored on the Bitcoin blockchain via OpenTimestamps.
Benchmark Report
This report documents three classes of performance tests following industry-standard SRE methodology (Google SRE Book, k6 test taxonomy). Raw results are hashed SHA-256 and anchored on the Bitcoin blockchain via OpenTimestamps — any alteration is detectable.

ABS Core was validated across three distinct test classes, each serving a different purpose for regulated-environment approval:
| Class | Load | Duration | Requests | Purpose |
|---|---|---|---|---|
| Endurance (Soak) | 200 req/s | 2h | ~1.44M | Stability over time, memory leaks, log growth |
| Load (Operational) | 1,000 req/s | 60 min | ~3.6M | SLO validation under real banking load |
| Stress | 5,000 req/s | 15 min | ~4.5M | Failure mode characterization, backpressure |
Why three classes? A risk committee cannot approve a system tested only at one load point. Each class answers a different question: Does it hold over time? Does it meet SLO at operational load? Does it fail gracefully under extreme load?
Test 1 — Endurance (Soak) · 200 req/s · 2 hours
Date: 2026-02-18 · Infrastructure: Cloudflare Workers (Global Edge)
Results
| Metric | Value | Assessment |
|---|---|---|
| Total Requests | ~1,440,000 | 200 req/s × 7,200s |
| Duration | 2h 00m | Full soak window |
| P50 Latency | 153ms | Stable — no drift over time |
| P95 Latency | 198ms | Within SLO envelope |
| P99 Latency | 247ms | P99/P50 ratio: 1.6x (excellent) |
| Errors (5xx) | 0 | Zero crashes in 2 hours |
| Throughput sustained | 200 req/s | No degradation detected |
| Memory growth | Flat | No leak observed |
Interpretation
The P99/P50 ratio of 1.6x is the critical stability indicator. Systems with ratio >3x exhibit jitter under sustained load — indicative of GC pressure, cache eviction, or connection pool exhaustion. At 1.6x after 2 hours and 1.44M requests, ABS Core demonstrates:
- No garbage collection pauses visible at the tail
- No progressive latency drift (common in systems with unbounded log queues)
- Consistent behavior across the full test window
Verdict for endurance: Passes SRE soak test criteria.
Test 2 — Load (Operational) · 1,000 req/s · 60 minutes
Date: 2026-02-25 · Infrastructure: Cloudflare Workers (Global Edge)
Results
| Metric | Value | Assessment |
|---|---|---|
| Total Requests | ~3,600,000 | 1,000 req/s × 3,600s |
| Duration | 60 min | Full operational window |
| P50 Latency | 161ms | Within SLO |
| P95 Latency | 224ms | Within SLO |
| P99 Latency | 289ms | Within SLO (threshold: 300ms) |
| Errors (5xx) | 0 | |
| Throughput sustained | 1,000 req/s | No shedding below rate limit |
| Rate limit activations | ~12% of requests | Expected — protects downstream |
Latency Distribution
| Percentile | Latency | Classification |
|---|---|---|
| Min | ~98ms | Best case (warm edge node) |
| P50 | 161ms | Median — operational baseline |
| P75 | ~194ms | Third quartile |
| P90 | ~218ms | High-load profile |
| P95 | 224ms | Enterprise-grade threshold |
| P99 | 289ms | Tail — within 300ms SLO |
| Max | ~744ms | Cold start (edge node wake) |
Comparison with Banking Operational Profiles
| Institution Profile | Typical Operational Load | ABS Core Tested | Coverage |
|---|---|---|---|
| Regional bank (R$ 500M/mo) | 80–200 req/s avg | 1,000 req/s | 5–12x headroom |
| Mid-size fintech (Pix-connected) | 200–600 req/s peak | 1,000 req/s | 1.6–5x headroom |
| Large bank (Pix-scale governance) | 800–2,000 req/s peak | Covered to 1k, stress to 5k | Partial — see Test 3 |
Verdict for load: Meets SLO at operational banking load. P99 < 300ms at 1,000 req/s sustained.
Test 3 — Stress · 5,000 req/s · 15 minutes
Date: 2026-02-26 · Infrastructure: Cloudflare Workers (Global Edge)
Results
| Metric | Value | Assessment |
|---|---|---|
| Total Requests | ~4,500,000 | 5,000 req/s × 900s |
| Duration | 15 min | Standard stress window |
| P50 Latency | 178ms | Graceful degradation (+17ms vs Test 2) |
| P95 Latency | 312ms | ⚠ Above 300ms SLO at extreme load |
| P99 Latency | 487ms | ⚠ Expected tail growth under saturation |
| Errors (5xx) | 0 | Zero crashes at 5x operational load |
| Rate limit activations | ~68% of requests | Backpressure working as designed |
| Circuit breaker trips | 0 | System self-regulated via rate limiter |
The 68% rate limit activation rate at 5,000 req/s is correct behavior.
The rate limiter is the first line of defense against DDoS and load spikes. At 5x operational load, the system deliberately sheds excess requests with HTTP 429 (Retry-After header) rather than allowing latency to spiral or returning 5xx errors. The 32% of requests that pass through are served within normal parameters.
This is the difference between graceful degradation and catastrophic failure — a core requirement for regulated environments.
Failure Mode Characterization
At 5,000 req/s, the system exhibited the following behavior:
- Rate limiter engaged at ~1,200 req/s (configured threshold), returning 429 with
Retry-After: 1 - No 5xx errors — the governance kernel never crashed or returned unhandled exceptions
- P50 drift of +17ms — acceptable for a 5x overload scenario
- P99 growth to 487ms — expected; tail latency is the first casualty of overload, P50 held
- Audit log integrity maintained — 100% of requests (passed + rejected) recorded in ledger
Stress Test Verdict
| Requirement | Threshold | Result | Pass/Fail |
|---|---|---|---|
| Zero 5xx under overload | 0 errors | 0 errors | Pass |
| Graceful degradation | Rate limit, not crash | HTTP 429 with Retry-After | Pass |
| Audit log integrity under stress | 100% recorded | 100% recorded | Pass |
| P50 stability | <2x normal P50 | 178ms vs 161ms (+10%) | Pass |
| Circuit breaker behavior | No cascading failure | Clean shed via rate limiter | Pass |
Verdict for stress: Failure mode is controlled and predictable. System sheds load via rate limiter rather than crashing. Suitable for regulated environments where graceful degradation is required.
Aggregate SLO Validation
| SLO Commitment | Target | Test 1 (200 rps) | Test 2 (1k rps) | Test 3 (5k rps) |
|---|---|---|---|---|
| P50 latency | <200ms | 153ms | 161ms | 178ms |
| P99 latency | <300ms | 247ms | 289ms | 487ms ⚠ (overload) |
| Error rate (5xx) | 0% | 0% | 0% | 0% |
| Availability | 99.95% | 100% | 100% | 100% |
| Audit completeness | 100% | 100% | 100% | 100% |
P99 note at 5,000 req/s: The 487ms P99 at 5x operational overload is expected and acceptable. The SLO of <300ms P99 applies to normal operational load (up to 1,000 req/s). At 5,000 req/s, the commitment is zero crashes and complete audit integrity — both maintained.

- Rate limiting was active during all tests — this reflects real production behavior
- Results include network latency from test runner to Cloudflare edge; pure compute latency is lower
- Stress test P99 (487ms) applies only at 5,000 req/s — 5x above designed operational load
- Cold start latency (max ~744ms) reflects first-request edge node initialization; subsequent requests are served from warm state

Note on Polygon L2: The optional on-chain anchoring feature uses Polygon Amoy — a public testnet — for Enterprise Early Access. This is disclosed as a preview capability. Production anchoring on mainnet is roadmapped. The Bitcoin OpenTimestamps proof above is the primary immutable integrity mechanism for all tiers.
