[SyntaxSidekick]

Labels: performance, database, priority-high, milestone-2

Large question database may cause loading delays and performance issues.

Current Performance Issues:

• All 40+ questions loaded at once
• No caching mechanism
• Database grows with each new question set

Optimization Strategy:

• Implement lazy loading by topic
• Add browser caching for question data
• Compress questionsDatabase.json
• Add loading states during data fetch
• Implement question preloading for smooth navigation
• Add error handling for failed loads

Technical Requirements:

• Modify questionDatabase.js for lazy loading
• Add React Suspense for loading states
• Implement service worker for caching
• Performance monitoring and metrics

Success Metrics:

• Initial load time < 2 seconds
• Topic switching < 500ms
• Offline capability for previously loaded topics

Priority: High - Performance impacts user retention
