Hi, > i have done quite some thinking lately how to speed up the [EMAIL PROTECTED] > upload. I've come up with an complete new structure of the server System.
There was a rather cool concept on the Wiki about a year ago where we would distribute tiles using DNS, i.e. you would always find the "responsible" server through DNS instead of through expensive database lookups and HTTP redirects. My personal thinking though is that we don't need a complex system like that because as soon as chrschmidt gets the new disks, everything is going to run smoothly again. A highly distributed concept, in my eyes, has one big drawback: We must assume that at any one time, a small percentage of tile servers will be down or slow. The usability of a map display is greatly reduced even if only one tile is missing. I would go so far as to say that a map consisting of 20 tiles, where one tile is a broken image, is a "failure". This means that if you get the tiles for one map display from 20 tile servers, then you have not a single point of failure, but 20 cascading single points of failure ;-) Bye Frederik -- Frederik Ramm ## eMail [EMAIL PROTECTED] ## N49°00'09" E008°23'33" _______________________________________________ Tilesathome mailing list [email protected] http://lists.openstreetmap.org/cgi-bin/mailman/listinfo/tilesathome
