latency 12ms
Without a cache, every request hits the database — load climbs and latency follows.
Your app is growing. Every page load fires queries at the database — and most of them ask for the same data, over and over.
- ▸Databases live on disk and parse every query — expensive by design
- ▸Under load, latency climbs from milliseconds to seconds
- ▸The kicker: the answer didn't change between requests — you paid full price to recompute the same result

Without a cache, every request hits the database — repeated identical queries waste resources and melt the DB under load.
