⚡ Performance Optimization (Quick Tips)

Keep it simple. Start with defaults, then tune only if needed.

✅ Recommended Settings

# Development (laptops)
CHART_MAX_CONCURRENCY=2
CHART_MAX_ROWS=100000

# Production (8–16 GB RAM)
CHART_MAX_CONCURRENCY=8
CHART_TOOL_TIMEOUT_MS=60000
REDIS_URL=redis://redis:6379

🧪 Monitor

docker compose logs -f
curl http://localhost:8000/health

🐛 If Slow

• Lower CHART_MAX_CONCURRENCY
• Reduce input size; aggregate before charting
• Prefer JSON/HTML over image formats during iteration

🧰 When Scaling

• Enable Redis cache (REDIS_URL)
• Increase CPU/RAM before tuning timeouts
• Horizontal scale HTTP service if needed
