A list that feels fast with a few hundred rows can become unusable once the data grows.
Loading everything into the browser and filtering locally increases memory use, exposes more data than necessary, and makes response time depend on the total table size.
Pagination, filtering, and sorting should happen at the server boundary when the volume justifies it. The UI should request the slice it needs and keep the query aligned with the user’s permissions.
Performance and security meet at the same boundary: retrieve only what the user is allowed to see and what the screen can actually display.
