How can caching make my app faster and cheaper?
If many visitors need the same slowly changing answer, such as exchange rates, fetch it once on the server and reuse it for a set time instead of calling a paid on every page view. Pages skip the wait and you pay for one call instead of thousands. Never put personal data in a shared cache.
Breaks at Your server: Same paid call on every page view
How it works
- Paid API calls
- 50,000
- Added to each page
- ≈ 780 ms
- Cost per day
- ≈ $25
Each column is an hour of visitors. Dark: a paid call. Yellow: answered from the cache.
Illustrative prices: $0.50 per 1,000 calls.

How to fix it
- Find outside calls made while building pages.
