I'm not sure, if this fits in here, but maybe you know something.
When playing with large mapsforge-files, like germany.map for example, I noticed some performance-issues on low levels.
Level 6 is the first, where major highways appear. When loading these tiles, I realized, that they include 10000th of ways, most of them with just a few nodes. This results in a huge amount of polylines to be drawn.
For me it looks, as if the level 6 contains all highways in full resolution.
Somehow I thought, during map-creation, ways are simplified according to the level to reduce the number of points for better drawing performance .
