OpenTopoMap very slow

[morphin]

Hi
I have a very fast internet connection, Browsing and Zooming opentopomap.org is very fast, immediately,
but in CMO i have to wait MINUTES to see if i zoom in. So there is an issue somewhere.
(Every zoom in i can go to make a coffe while waiting for the map to download)

Solution: Make it available offline please. I would like to play and not waiting and waiting for houres to download the maps....

You see in the attachment a short video clip

Please

Thank's
