Caching
Caching stores frequently accessed data temporarily in fast storage (like Redis or memory) to reduce database load and improve response times.
Why It Matters
Proper caching can reduce page load times from seconds to milliseconds while dramatically reducing server resource usage.
When to Use This
- Reducing database queries for slow-changing data
- Storing API responses to avoid repeated external calls
- Speeding up expensive calculations
- Improving user experience with faster page loads
Examples
- Caching the menu for 1 hour instead of querying it on every page load
- Storing third-party API responses for 5 minutes
- Cache warming on deployment for instant fast loads
