--- Comment #1 from b. <newbie-02 at gmx.de> ---
actual observations: 

the probems had been significantly better in ver. 6.2.7.1 for win (x64), 

(not better problem, but working better), 

it had not been solved in that version, but reduced to a usable state, 

in ver. 6.4.0.0a1 it's a 'better problems' again, i guess the performance loss
has about doubled. 

i hope that the information will help to narrow down the source of the evil by
comparing the versions.

observations: 

fresh loaded file with 40k commented cells: 

in 6.2.7.1 win (x64): 

'little' system load when circling around with the mouse, about 3 to 4%
(task-manager), 
!! thats about 25% of the max. of 12% what calc is able to take on a 8 core
system !!, 
doubled to 4 to 8% after 'save a copy', 

nearly no delay of the 'focus' (selected cell) following a mouseclick, 
little delays to see after 'save a copy', 


in 6.2.7.1 lin: 

stopped testing after incredible delays just with 10k commented cells, 


in 6.4.0.0a1

'medium' system load when circling around with the mouse, about 8%, 
increased to 12% after 'save a copy', 12% is max load calc can take, 

little delay of the 'focus' (selected cell) following a mouseclick on a loaded
file, about 1 sec. delay per 10k cells when you create them in a fresh
document,  
increased to 4 seconds (10k cells) to 10 seconds (40k cells) delay after 'save
a copy', 

derivations - assumptions: 

there is a difference in handling between win and lin, once found it's possible
to improve the other platform, 

there are superfluous calculations for mousemoves, 

there are superfluous calculations for commented cells, 

the bad influence worsens after every backup of the file, both 'save' and 'save
as', as well as 'save a copy' increase the performance losses, there is
probably an ineffective handling of the data. 

anybody fit enough to 'take that'?
