Hi, 

I got this Big Data effect with slow down and annoying speedloss also.
(35000 rows and 64 Columns mixed data, text and numbers, 3 to 5 sheets in one
ODS file)

I filled up the sheets with simple formatted Data, no formula, only to sort the
columns for creating clean CSV files. This is a great function of libre Office
calc also the field formatting I love.

1. First I killed all automatic spellchecking, this helped ... I was thinking
for a moment ... very good.

Then I go ahead with editing and like joshas speek, the scolling gots crazy.

2. I pressed the down key to step line by line ... no effect or extremly slow.

3. Then I checked the mouse on the right slider, and this was a big mistake.
Then the table was fully grey no fillings and the slider on right side
constantly jumps slowly, I guess page by page, unvisible up or down depends on
the direction I clicked before.
After 5 Minutes I killed the task. Good luck no data loss. 

I repeated, after restart, my checks, but now I give up.
The saving of the sheets shows in the same way big loss of speed.

Doing the same work in MS Excel, I can run additional functions, macros and VBA
scripts without any bad effect like this. 

I hope you will find the solution ....
