  tags: [performance, optimization]

objective:
- Optimize performance and establish benchmarks

deliverables:
- Performance benchmarks: `android/src/androidTest/java/com/rssuper/benchmark/PerformanceBenchmarks.kt`
- Benchmark suite covering all acceptance criteria
- Platform-specific profiling setup

tests:
- Benchmark: Feed parsing <100ms
- Benchmark: Feed fetching <5s
- Benchmark: Search <200ms
- Benchmark: Database query <50ms
- Memory: No leaks detected
- CPU: Efficient usage

acceptance_criteria:
- Feed parsing <100ms for typical feed
- Feed fetching <5s on normal network
- Search <200ms
- Database queries <50ms
- No memory leaks
- Smooth UI at 60fps
- Battery efficient

validation:
- Run benchmarks on each platform
- Profile with Instruments (iOS)
- Profile with Android Profiler
- Profile with Valgrind (Linux)

notes:
- Use platform-specific profiling tools
- Establish baseline metrics
- Optimize iteratively
- Document optimizations made
