        <pre>Description:
i have a performance issue discussed in #124692, 

from latest tests i assume it resulting from plenty comments spread in the
file, 

i can provide two test files - see next two comments - one with ~ 80 comments
spread in A:J, and the other a copy where the comments are stripped out. 

pls. look at them and observe the cpu load (windows taskmanager) which occurs
when just clicking around in the visible part of the sheet. 

i got significant differences, especially after minor changes in the files and
the first subsequent autosave (autosave has to be on to see it). 

any help appreciated, and i think it'll make the program better when this
problem is out. 

reg. 



b. 

Steps to Reproduce:
1. see description
2.
3.

Actual Results:
clicking in file with comments slower and producing cpu load

Expected Results:
no or neglectable difference in performance regarding comments contained in the
file, as it was with former versions,
