# Task ID: 19
# Title: Initial Performance Optimization & Bug Fixes
# Status: pending
# Dependencies: 15, 18
# Priority: high
# Description: Conduct initial performance profiling and address critical bugs identified during MVP development. Focus on improving client-side rendering, network latency, and overall responsiveness.
# Details:
Frontend: Optimize rendering of `GameBoard` and `PlaneSprite` components (e.g., memoization, use of `requestAnimationFrame`). Implement message compression for WebSocket. Backend: Review database queries for efficiency (indexing). Monitor server CPU/memory usage. Address any reported bugs. Ensure client-side loading times (<2s first screen, <300ms page switch) and stable 60fps.

# Test Strategy:
Use browser/mini-program developer tools to profile rendering performance (FPS, repaint times). Monitor network requests for latency and payload size. Conduct stress tests on the backend. Perform thorough QA testing to identify and verify bug fixes.
