Hi, I am planning to set up a map tile server and I was going through forum articles on improving tile rendering performance. Is pre-rendering tiles to a certain zoom level a prerequisite for tile rendering performance or using indexes and fine-tuning Postgres DB we can achieve the required performance expectations? asked 09 Nov '20, 08:05  jchrisprabu |
One Answer:
Rendering tiles on zoom levels <= 8 will always be very slow, and several modifications are required to the osm-carto style if you want to render these "on the fly" with acceptable performance. Generally, pre-rendering the world on z0-12 is recommended when you set up a tile server. You can get away with less but you are very unlikely to get away without pre-rendering z0-8 at least. answered 09 Nov '20, 08:40  Frederik Ramm ♦ |
