--- Comment #5 from b. <newbie-02 at gmx.de> ---
@Telesto: win repro, lin not, 

win: 

~5 seconds, slower on subsequent tries, adds up to ~12 seconds, 

lin: 

no repro, milliseconds

additional note(s): 

my construction 
"=CHAR(INT(RAND()*26+1+96))&CHAR(INT(RAND()*26+1+96))&CHAR(INT(RAND()*26+1+96))&CHAR(INT(RAND()*26+1+96))&CHAR(INT(RAND()*26+1+96))" 
is - intentionally! - nagging spreadsheets, for productive use read and keep in
mind:

observe: from undo you don't get back the previous state, but fresh calculated
random values. maybe in win 'rand' is a little slower? 

prev. likely not the issue here as: 

with win after one copy and paste to other columns: 

much better performance even with 10 times the data, ~ 2 seconds ...???
**confused**
