Performance Benchmarks

This document tracks performance metrics for react-native-sync-vault.

Target Metrics

  • Initialization time: < 50ms
  • Memory overhead per queued request: < 1KB
  • Enqueue time: < 5ms
  • Batch sync time: < 100ms per batch of 5 requests

Baseline Metrics

Initialization

  • Target: < 50ms
  • Current: TBD (measured during first initialization)
  • Notes: Includes database initialization and schema setup

Memory Overhead

  • Target: < 1KB per queued request
  • Current: TBD
  • Notes: Includes request metadata, headers, body, and status information

Enqueue Operation

  • Target: < 5ms
  • Current: TBD
  • Notes: Time to queue a request and persist to SQLite

Sync Operation

  • Target: < 100ms per batch of 5 requests
  • Current: TBD
  • Notes: Time to process a batch of requests (network time excluded)

Performance Tracking

Performance metrics are tracked automatically and can be accessed via:

import { performanceTracker } from 'react-native-sync-vault';

const metrics = await performanceTracker.getMetrics();
console.log('Initialization time:', metrics.initializationTime);
console.log('Average enqueue time:', metrics.averageEnqueueTime);
console.log('Average sync time:', metrics.averageSyncTime);

Optimization Strategies

  1. Database Indexes: All frequently queried columns are indexed
  2. Batch Operations: Multiple database operations are batched when possible
  3. Efficient Serialization: JSON serialization is optimized
  4. Progressive Sync: Requests are processed in batches to avoid blocking

Future Optimizations

  • Turbo Module migration for reduced bridge overhead
  • JSI bindings for direct native access
  • Connection pooling for database operations
  • Request deduplication optimization

Testing

Run performance benchmarks:

npm run test:performance

CI Integration

Performance regression tests are run in CI to catch performance degradation.
