Openstreetmap vs Opencyclemap (Rendering speed)

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?



Are you talking about the speed you get when you drag the map on the webpage, or the speed with which the tiles are loaded? They don’t use the same servers, but they should use the same javascript setup…

Yes, the speed when I drag the map. I think there’s a significant difference.
