typing messages is very sluggish whilst pages are loading
How do you mean?

Yes, I was busy copying images to this new install, so one wouldn't even notice. But the copy proces was very slow (10's of hours and just passed 50%). I'm going to do a folder move, that is a thing that can't be done in advance nor is the current FTP tool capable to do it (:/). The dump download is at 50% now. After that I'll swap to the other PC and sort the layout.
