Loading too much data at once will inevitably slow down. And without the template engine, the rendered template will not be cached, and each request will be rendered once, and will certainly be slow.
We recommend using the template engine to turn on the engine cache.
Do not fetch too much data from the database at once, and pull the data from the background with several async. Reduces pressure on first load. Data that is not constantly changing should also be cached.
