I have mentioned this behavior in other reports.

STR:
1. Open  attachment 193900.
2. [CTRL]+[HOME].
3. During 10 seconds, press and hold the [PageDown] key.
4. At the 10 seconds stopper/timer, release the [PageDown] key and take note of
the row number of the active cell.
5. Select All cells – click the area at the intersection between Column headers
and Row headers.
6. Menu Format > Columns > Show.

Now we repeat the procedure:

7. [CTRL]+[HOME].
8. During 10 seconds, press and hold the [PageDown] key.
9. At the 10 seconds stopper/timer, release the [PageDown] key and take note of
the row number of the active cell.

Now compare the row numbers, between step 4 and step 9.

For me, the current ratio is around 1:8 approximately.

So, without having hidden columns at the "end" of the worksheet (inactive
area), Calc scrolls 7/8 times faster than when I have the inactive area hidden.

A similar test can be performed when having the "inactive" rows as hidden
instead of hidden columns.

Testing in Safe Mode produced the same results.

I have attempted to create and attach a suitable sample file.
