Labels

Tests label speed rendering.

Points (w/o marker, just labels)

z/x/y tiles:

Lines

Test canada-road-map, from zoom 18 to zoom 0 and given a bounding-box it iterates over a predefined bounding-box to request meaningful tiles (non empty tiles), instead of looping over the whole quad-tree.

30 seconds, 4 threads

Bounding-box: Central Canada

Node v0.10.26 / Mapnik 2.3.x / lines / canada road network / default style

Empty map benchmark

Test an empty map (no data, no style), from zoom 18 to zoom 0 and given a bounding-box it iterates over a predefined bounding-box to request tiles, instead of looping over the whole quad-tree.

30 seconds, 4 threads

Bounding-box: Spain

Node v0.10.26 / Mapnik 2.3.x / no features / empty map / no style

Geology of Spain benchmark

Test spain-geology-map, from zoom 18 to zoom 0 and given a bounding-box it iterates over a predefined bounding-box to request meaningful tiles (non empty tiles), instead of looping over the whole quad-tree.

30 seconds, 4 threads

Bounding-box: Spain

Node v0.10.26 / Mapnik 2.3.x / polygons / geology of spain / custom style

Pluto benchmark

Test pluto-map, from zoom 18 to zoom 0 and given a bounding-box it iterates over a predefined bounding-box to request meaningful tiles (non empty tiles), instead of looping over the whole quad-tree.

Complete cycle (about 90k tiles)

CartoDB's MVT service + Mapbox GL

Check index.html for some examples. These use a beta feature of CartoDB's Maps API: fixed URLs. So there is no need to use cartodb.js and tiles can be consumed using a named map name.

cartodb.js example

Check cartodb.js.html to see the integration with cartodb.js and in particular with cartodb.core.js.
