But why is your query so slow? Optimized query with correct use of indexes should be really fast, despite of data amount.

In addition to commercial software, it's possible to write to write application for that, using open source components like OpenLayers and GeoServer. There are also lot of existing applications, take a look here: gis.stackexchange.com/questions/43477/…

comment What is “n” in calculating tiles?
@whuber Could you explain, what's backwards? Zoomlevel = 5, n = pow(2, 5) = 2^5 = 32, meaning, that there are 32x32 tiles in that level.

comment Best way to create tiles
Since you are using GeoServer, GeoWebCache would be obvious choice.

Yes, it's good to point out, that those formulas work only with R, R/2, R/4 scenario. But (as said in my post), number of tiles can be calculated with pow(pow(2, zoom), 2) or pow(2, zoom*2).
