That is hardly surprising, if you consider what Emacs needs to do when
large portions of the buffer are not shown: it needs to find the next
visible line by scanning all the invisible ones in between.  So the
more text is folded, the slower will be the display.

Because it doesn't try to preserve the column and support continued
lines the way next-line and previous-line do.  It simply goes to the
next heading by regexp, then checks if that heading is visible, and if
not continues to the next one.
