Static rendering and revalidation
Pages built ahead of time and refreshed on a schedule or on demand.
What it is
Static rendering builds a page once and serves the result to everyone; revalidation rebuilds it when the data changes or after an interval, rather than on every request.
Why it costs you money
It is what makes a decoupled storefront fast without hammering the commerce backend. The trade-off is freshness, which is why price and stock are the fields that need care.
How to check it yourself
Cache catalogue content aggressively, invalidate on product updates, and check price and stock live at the moment of adding to cart.
