[Tilesathome] Some First Day Stats

[Brent Easton]

Hi Johan,

That's one possiblity. Once the initial .osm file has been downloaed, the client could perhaps use soem sort of rule of thumb to determine if it can attempt it.

The disadvantage of course is that the client has download the data from OSM before it can reject it. High resource tiles might bounce around several clients, all downloading the data and rejecting it before one eventually processes it.

Perhaps the too_complex_for_me for me response by the first client back to the client could include a 'complexity' rating that the server then attaches to the request, and then from then on, that request can only be handed out to 'high resource' configured clients. Perhaps the server could even record that in a db for future reference? (The land/sea/mixed status could be recorded there also???).

Just ideas to toss around,

Cheers,
Brent.
