I'm at 10 minutes now, for a town of <15k. Render time might depend more on total area than number of lines to draw. Update: gave up after 20min. Something might be wrong with the particular city.
Render time for Seattle is a blink of the eye which has both area and density. I think the time people is observing is loading the raw data from open street map itself.
Because they cache the biggest cities in the world.

About 2 seconds for me to load and draw Los Angeles. It’s definitely the load time/network latency, depending on where it’s loading from. This is amazing! I might use it for a custom map or something
