I think the splitting is done automatically based on map feature density?

Indeed, I'm trying to create tiles with maximum tile area because the maps created by Mkgmap have (had? Don't recall exactly from the top of my head.) problems routing over more then one tile edge. This might not be a problem in Asia where the data density is mostly not very high, but caused many problems in Western Europe. Also, but this is not an issue anymore, earlier versions of the tools to create the maps could handle only 255 tiles (there are about 800 now).

I was suggesting that popular map requests be pre-compiled and mirrored to take load off the server. Lambertus is correct that some sets are available elsewhere for some countries and regions but not all. And many countries do not provide a mapsource-installer format.

Fair point, but could partly be a chicken and egg problem. Alternatively I could just stop providing maps for Europe and North America.

However I totally understand and agree with Lambertus' reply. This is indeed a unique service, the core issue is that it's become too popular for the available resources.

Thanks. Limits have been hit before and each time a solution has expanded usability, functionality and allowed even more users, but now that the low hanging fruit has been eaten it just gets a bit more difficult to improve. Improvements should still be possible though, I like greencaps' suggestion.

Another idea might be to offload the maps to an alternative hosting provider once they're compiled, that way your own disk remains relatively clean.

This suggestion is interesting. I reckon it's susceptible to break-down and requires quite a bit of bookkeeping but it could move the limit a bit further. Pure hosting (without the CPU cycles for map generation) is cheap, at least in the USA and -like you- there should be some people who would contribute some spare space. Yes I like it, but as always, it will take time to develop.
