When systems slow down, the first instinct is usually:
“Let’s add more cache.”
That helps — until it doesn’t.
At scale, read performance is rarely limited by a single slow component.

Capacity estimation is often treated like a warm-up exercise in system design. A few numbers. Some back-of-the-envelope math. Then straight to architecture diagrams. That approach misses the point...
