I think browsing will get slightly faster too: - extra overhead for one tile is only 4KB, it's propably less than overhead for getting file in filesystem with millions of files - there will be much smaller number of files - much bigger change filesystem metadata will fit into memory cache - no need to look for blank land/see tiles in mysql for z12 and bigger zooms - tiles for higher zooms are often from one tileset - bigger change data are already in cache > I asked a bit on #osm, and it seems the current problem is basically > the write speed on the drive where tiles are stored.

It's much faster to save one big file than 1000 small files with the same total size because saving 1000 files require lots of hdd seeks. > > > Btw. At first I've sent this to Alan only.

I don't think that using Reply-to-all will make people think more about what they're sending. Anyway, if administrators think having no reply-to header is good idea then I will just try to get used to it. > -- > Knut Arne Bjørndal > aka Bob Kåre > [EMAIL PROTECTED] > [EMAIL PROTECTED] > > _______________________________________________ Tilesathome mailing list [email protected] http://lists.openstreetmap.org/cgi-bin/mailman/listinfo/tilesathome
