After this, informationfreeway.org is a lot slower. I reload the
page and it takes 15 seconds or more before all tiles have arrived
from the dev server. What new value did you set? Could you
please increase it a little again, to see if this helps?

Is this the case on any normal day, or only now for the sea tiles?

What scheduler are you talking about here? I thought all t at h
tiles were generated "at home" and then uploaded to the server.
Is there also a process running on the server to generate tiles?
