do you have a tirex setup? It includes tools to request render of
certain areas and zoom levels.
You could pre-render the lowzoom tiles as these change less frequent and
are more expensive to render.
Use clever tile expiry and update strategy.
Then prerender the most important area on the map. If someone requests
other areas these tiles will be freshly rendered and cached.
This can be tunes to match your disk space and rendering speed capabilities.
For example the following commands renders the global lowzoom and in
detail the most important parts of Southeast Asia:
tirex-batch --prio=25 map=osm bbox=-180,-90,180,90 z=0-8
tirex-batch --prio=25 map=osm bbox=97.33,5.6,105.66,20.47 z=9-18
