Why not ask your question on the new OpenStreetMap Community Forum?

I have implemented a tile server. But I haven't build any tile cache yet. For the very first time when I open a tile in browser, it took around 53seconds to load for a single tile(256*256, zoom level 1, openstreetmap carto style ).

My question is - Is this time taken normal? or Should I look into my Postgres configuration to further minimize the time. And Is there any minimum time for tile loading(without any prerender or cache) that can be achieved using postgres tuning?

What zoom level and what stylesheet?

zoom level one. openstreet carto style

This is strongly dependent on the zoom level we are talking about.

Fastest rendering would be in "high" zoomlevels like 18 or 19:

> time render_single_tile.py s osm.xml -o out.png -u /19/274383/180030.png real 0m11.298s user 0m1.152s sys 0m0.316s

If you give me an exact tile URL I can check how long it takes on my tileserver.

In case you wonder where to get render_single_tile.py have a look at
