 Production-quality hosting of 300 million tiny files is hard. The average file size is just 450 byte. Dozens of tile servers have been written to tackle this problem, but they all have their limitations.
 
-The original idea of this project is to avoid using tile servers altogether. Instead, the tiles are directly served from BTRFS partition images + hard links using an optimised nginx config. I wrote [extract_mbtiles](scripts/tile_gen/extract_mbtiles) and [shrink_btrfs](scripts/tile_gen/shrink_btrfs) scripts for this very purpose.

 This replaces a running service with a pure, file-system-level implementation. Since the Linux kernel's file caching is among the highest-performing and most thoroughly tested codes ever written, it delivers serious performance.

 Unfortunately, when you want to use the map on your website or app, you need to look for a commercial map tile provider and hope your site doesn't become too popular. Otherwise, you might end up with a $10,000 bill in a single day, as Hoodmaps [did](https://x.com/levelsio/status/1730659933232730443).
