[Tile-serving] Need tiles levels 0-10 for offline access

[Paolo Maffei]

Hello,
we are developing an offline application that will need to access the world
map from level 0 to 10.

We use OpenLayers on the client and will be using a simple TMS style
protocol over HTTP to serve tiles.

We've been trying to generate a world map with MapTiler and GDAL2tiles,
neither had any success (it just crashes our machines or timeouts).
I believe this might be because it is a very big task to generate this many
tiles (is this the case or we are doing something wrong?)

I was wondering what would be the best way to obtain these tiles?
Would downloading them from OpenStreetMap API be a good idea?

Thank you,
Paolo
