The MetricsCollector, reporter, client-pool, page objects, and CI workflow are all in place. + +## Common Pitfalls + +### Pitfall 1: Performance API Not Available + +**What goes wrong:** `performance.mark()` throws in environments where the Performance API doesn't exist (e.g., some SSR contexts, older Node.js). +**Why it happens:** sdk-core is a library that could be imported anywhere. +**How to avoid:** Guard all Performance API calls behind a `typeof performance !== 'undefined' && typeof performance.mark === 'function'` check, evaluated once at module load. +**Warning signs:** `ReferenceError: performance is not defined` in test output. + +### Pitfall 2: Mark Memory Accumulation + +**What goes wrong:** Thousands of `performance.mark()` entries accumulate during load tests, causing memory pressure. +**Why it happens:** Marks persist in the Performance Timeline until explicitly cleared. +**How to avoid:** Call `performance.clearMarks()` and `performance.clearMeasures()` after each measurement. The `withPerf` wrapper should handle this automatically. +**Warning signs:** Increasing memory usage during sustained load tests. + +### Pitfall 3: Threshold Flakiness in CI + +**What goes wrong:** Load test thresholds pass locally but fail in CI due to different hardware characteristics. +**Why it happens:** CI runners have less CPU/RAM/disk throughput than dev machines. Network latency to external services varies. +**How to avoid:** Set thresholds at 2-3x observed values. Use error rate thresholds alongside latency thresholds. Load tests run on `workflow_dispatch` (manual trigger), not on every push. +**Warning signs:** Intermittent CI failures on the same code. + +### Pitfall 4: Playwright Timing Includes Rendering + +**What goes wrong:** Journey timings seem high because they include browser rendering, paint, and layout. +**Why it happens:** Playwright measures from action to visible result, which includes all browser work. +**How to avoid:** This is intentional -- journey timing should capture the user experience, not just API latency. Document that timings include rendering. Compare to SDK-level timings separately. +**Warning signs:** Upload-to-visible time is much higher than SDK upload time. + +### Pitfall 5: Share-to-Accessible Journey May Not Be Testable + +**What goes wrong:** The "share-to-accessible" journey requires two accounts and cross-account verification. +**Why it happens:** Sharing features require a second user to accept and access the shared folder. +**How to avoid:** Use the existing `sharing-workflow.spec.ts` E2E test as a reference for the multi-account pattern. The wallet-login helpers support creating multiple test accounts. +**Warning signs:** Single-account test patterns don't cover the share recipient flow. + +## Code Examples + +### Instrumenting an sdk-core Function + +```typescript +// packages/sdk-core/src/upload/index.ts (modified) +import { withPerf } from '../perf'; + +export async function uploadFile(params: { ... }): Promise { + return withPerf('upload:full', async () => { + const fileKey = generateFileKey(); + const iv = generateIv(); + + try { + // Wrap individual sub-operations + const ciphertext = await withPerf('encrypt:aes-gcm', () => + encryptAesGcm(params.data, fileKey, iv) + ); + + const wrappedKey = await withPerf('encrypt:ecies-wrap', () => + wrapKey(fileKey, params.userPublicKey) + ); + + const { cid, size: encryptedSize } = await withPerf('ipfs:upload', () => + addToIpfs(params.ctx, ciphertext, params.onProgress) + ); + + const fileMetaResult = await withPerf('ipns:file-meta-create', () => + createFileMetadata({ ... }) + ); + + return { cid, encryptedSize, ... }; + } finally { + clearBytes(fileKey); + } + }); +} +``` + +Source: Derived from existing `packages/sdk-core/src/upload/index.ts` structure. + +### Reading Performance Measures Programmatically + +```typescript +// In browser DevTools console or test code: +const measures = performance + .getEntriesByType('measure') + .filter((e) => e.name.startsWith('cipherbox:')); + +for (const m of measures) { + console.log(`${m.name}: ${m.duration.toFixed(2)}ms`); +} +// Output: +// cipherbox:encrypt:aes-gcm: 12.45ms +// cipherbox:ipfs:upload: 1502.30ms +// cipherbox:upload:full: 1623.80ms +``` + +Source: [MDN Performance API](https://developer.mozilla.org/en-US/docs/Web/API/Performance/measure) + +### Threshold-Gated Load Test + +```typescript +// tests/load/src/scenarios/upload-throughput.test.ts (enhanced) +import { expect } from 'vitest'; +import { checkThresholds, type ThresholdConfig } from '../harness/thresholds'; + +const THRESHOLDS: ThresholdConfig[] = [ + { operation: 'uploadFile', p95MaxMs: 10_000, errorRateMax: 0.05 }, +]; + +// After aggregateAndReport: +const metrics = await aggregateAndReport('Upload Throughput', pool); +const result = checkThresholds(metrics, THRESHOLDS); + +if (!result.passed) { + console.warn('THRESHOLD VIOLATIONS:'); + result.violations.forEach((v) => console.warn(` - ${v}`)); +} +expect(result.passed, `Thresholds breached:\n${result.violations.join('\n')}`).toBe(true); +``` + +### Playwright Journey Timing Output + +```typescript +// tests/web-e2e/tests/journey-timing.spec.ts + +import { test, expect } from '@playwright/test'; +import { LoginPage } from '../page-objects/login.page'; +import { setupMockWallet, loginViaWallet } from '../utils/wallet-login-helpers'; + +test.describe.serial('Journey Timing', () => { + test('login-to-vault', async ({ page, context }) => { + const account = createTestAccount(); + await setupMockWallet(context, account); + + const start = performance.now(); + + // Login phase + const loginStart = performance.now(); + const loginPage = new LoginPage(page); + await loginPage.goto(); + await loginViaWallet(page); + const loginMs = performance.now() - loginStart; + + // Vault load phase + const vaultStart = performance.now(); + await page.waitForSelector('[data-testid="file-list"]', { timeout: 30000 }); + const vaultLoadMs = performance.now() - vaultStart; + + const totalMs = performance.now() - start; + + // Output for baseline capture + console.log( + `JOURNEY_TIMING: ${JSON.stringify({ + journey: 'login-to-vault', + totalMs: Math.round(totalMs), + loginMs: Math.round(loginMs), + vaultLoadMs: Math.round(vaultLoadMs), + })}` + ); + + // Sanity check -- should complete within 60s + expect(totalMs).toBeLessThan(60_000); + }); +}); +``` + +## State of the Art + +| Old Approach | Current Approach | When Changed | Impact | +| ----------------------------------- | -------------------------------------------- | ------------ | ------------------------------------------------------- | +| `Date.now()` for SDK timing | `performance.now()` (existing withOperation) | Phase 19.1 | Sub-ms resolution but no DevTools integration | +| Manual baseline comparison | Automated threshold checking in CI | Phase 22 | Regressions caught automatically instead of manually | +| Server-side only Prometheus metrics | Client + server instrumentation | Phase 22 | Full pipeline visibility (encrypt -> upload -> publish) | +| Ad-hoc load test runs | Threshold-gated CI workflow | Phase 22 | Pass/fail automation prevents regression merges | + +**Deprecated/outdated:** + +- Phase 18 `scripts/baseline-benchmark.sh` (curl-based): Replaced by SDK-level load tests which capture the full client pipeline including crypto.

Infrastructure Bottlenecks + +### 2.1 Kubo IPFS Node + +Kubo's `pin add` operation is the **dominant bottleneck**, consuming ~95% of upload endpoint latency. Each `uploadFile` SDK call requires 3 sequential pin operations (ciphertext, file metadata, folder metadata), totaling ~4-5s server-side at mean. + +**Optimization impact (pebbleds datastore):** + +| Metric | flatfs (pre) | pebbleds (post) | Change | +| -------------------- | ------------ | --------------- | ---------- | +| Pin mean latency | 1.73s | 1.37s | -20.8% | +| Pin p50 (estimated) | ~1.7s | ~1.0s | -41% | +| IPNS publish mean | ~120ms | ~50ms | -58% | +| 75-client errors | 10 | 0 | Eliminated | +| 75-client throughput | 2.44 ops/s | 3.51 ops/s | +43.9% | + +Concurrent pins from multiple clients cause contention on the Kubo datastore. At 50 clients, throughput plateaus at ~3.4-3.7 ops/s locally and ~15-19 ops/s on staging. At 75 clients with flatfs, errors begin appearing; pebbleds eliminates this failure mode entirely. + +**Memory and CPU:** Kubo uses Go's goroutine scheduler. Pin operations are I/O-bound on the datastore. The pebbleds LSM-tree datastore batches writes, reducing I/O contention under concurrent load. + +### 2.2 PostgreSQL + +Auth lookups, IPNS record cache reads/writes, and vault operations are fast: + +| Operation | Mean Latency | +| ---------------- | ------------ | +| Vault lookup | < 5ms | +| Quota check | < 5ms | +| IPNS DB resolve | 23-36ms | +| IPNS DB upsert | ~50ms | +| Auth login (JWT) | 104-155ms | + +PostgreSQL is **not the bottleneck** at current scale. The `folder_ipns` table grows linearly with `users x folders`, but even at 200 concurrent clients, DB operations remain sub-100ms. + +**Connection pooling:** TypeORM manages the connection pool. Default pool size handles current concurrency levels without exhaustion. + +### 2.3 API Server (NestJS) + +Request processing overhead is minimal (~5-10ms per request excluding downstream IPFS/IPNS calls). The API server acts primarily as a pass-through to Kubo for IPFS operations and to PostgreSQL for IPNS record management. + +- **Rate limiting:** ThrottlerGuard protects against abuse. Load tests bypass throttling via `THROTTLE_BYPASS_SECRET` in test mode. +- **Connection handling:** NestJS handles concurrent HTTP connections efficiently. No observed issues at 200 concurrent clients. +- **CPU:** Not a bottleneck. Server-side processing time per request is dominated by Kubo pin latency, not application logic. + +### 2.4 Redis + +Used for rate limiting state and session management. Sub-millisecond operations. Not a bottleneck at any observed concurrency level. + +### 2.5 Someguy (Delegated Routing Sidecar) + +IPNS publish DHT propagation happens asynchronously and does not block client responses.

Someguy's warm DHT is critical for IPNS resolution performance in non-API contexts (recovery tool, TEE republishing). + +--- + +## 3. Scaling Recommendations + +### 3.1 When to Scale + +| Signal | Threshold | Action | +| ------------------------------------------ | ---------------------- | ------------------------------------------ | +| Upload p95 > 5s consistently (staging) | Kubo pin contention | Add second Kubo node or upgrade hardware | +| Upload p95 > 15s consistently (staging) | Kubo saturated | Kubo cluster mode or dedicated pin workers | +| API response time p95 > 500ms (non-IPFS) | API CPU bound | Add API replica behind load balancer | +| PostgreSQL connections > 80% pool | DB saturated | Increase pool size or add read replica | +| Kubo datastore > 80% disk | Storage full | Expand volume or enable garbage collection | +| IPNS publish queue depth > 100 | Publish backlog | Tune Kubo worker concurrency | +| Mixed workload error rate > 1% | Infrastructure ceiling | Scale horizontally (Kubo + API) | +| Throughput plateaus despite adding clients | Single-node ceiling | Horizontal scaling required | + +### 3.2 How to Scale + +**Kubo IPFS Node:** + +- **Vertical:** Increase CPU/RAM/SSD. Pebbleds datastore benefits significantly from faster I/O. Move from HDD to NVMe SSD for pin operations. +- **Horizontal:** Run multiple Kubo nodes behind the API. Each API instance pins to a designated Kubo node. Requires content routing coordination (IPFS Cluster or custom routing). +- **Cluster mode:** [IPFS Cluster](https://cluster.ipfs.io/) adds pinning coordination but introduces operational complexity. Recommended only when single-node Kubo reaches sustained saturation. + +**API Server (NestJS):** + +- The API is stateless (session state in Redis, no in-memory state). Adding replicas behind Caddy or nginx is straightforward. +- Ensure all replicas share the same Redis instance for rate limiting and session consistency. +- Database connection pool per replica needs coordination (total connections = replicas x pool_size). + +**PostgreSQL:** + +- **Read replicas:** IPNS cache reads can be directed to read replicas. Write scaling is unnecessary at current volume. +- **Connection pooling:** Use PgBouncer if connection count exceeds PostgreSQL's `max_connections`. +- **Sharding:** Premature for a tech demo. Only consider if user count exceeds ~100,000. + +**TEE Republishing:** + +- Independent scaling path. Add TEE workers to increase IPNS republish batch throughput. +- Each TEE worker processes a batch of IPNS names every 3 hours. +- Batch duration grows linearly with IPNS name count. Monitor `cipherbox_republish_batch_duration_seconds`. + +--- + +## 4.

Load Test Thresholds + +Automated pass/fail thresholds are defined in `tests/load/src/harness/thresholds.ts` and integrated into all 5 load test scenarios.

If any threshold is breached, the test fails with a descriptive violation message listing the operation, observed value, and threshold +4. The CI workflow (`load-test.yml`) runs via `workflow_dispatch` (manual trigger), not on every push + +**Updating thresholds:** When baselines shift significantly (new infrastructure, new optimizations), update the threshold values in each scenario file.
