I was testing both sites here one day, and I noticed a big difference in smoothness.
While opencyclemap renders almost perfectly smooth, openstreetmap lags a lot.
What’s the reason for this? As far as I see, they are using the same tile servers.
I’m considering setting up my own server using Mapnik, and I’m therefore curious.
Anyone knows what tools opencyclemap are using, and why there’s such a difference?
