# SuperSync E2E Test Performance - Baseline Measurement

**Date:** 2026-01-18
**Total Duration:** 10:34.81 (634.81 seconds)
**Test Results:**

- 42 passed
- 81 skipped
- 4 flaky (infrastructure issues - SuperSync server became unhealthy mid-run)

**Flaky Tests:**

1. `supersync-encryption.spec.ts` - Encrypted data fails to sync with wrong password
2. `supersync-error-handling.spec.ts` - Concurrent modification triggers LWW conflict resolution
3. `supersync-error-handling.spec.ts` - Three clients converge to same state
4. `supersync-import-clean-slate.spec.ts` - Import drops ALL concurrent work (clean slate)

**Average per-test time:** 634.81 / 127 = ~5 seconds per test

**Note:** The flaky tests failed due to SuperSync server health issues (ECONNREFUSED), not test logic.

## Optimization Targets

Based on the plan:

- **Conservative:** 25% reduction → ~8 minutes (476 seconds)
- **Optimistic:** 40% reduction → ~6.3 minutes (381 seconds)

## Phase 1 Optimizations

Starting Phase 1 with 4 sub-tasks to reduce wait times systematically.
