<pre>Description:
this posting is related to a very old <a class="bz_bug_link
bz_status_NEW "
title="NEW - CALC becomes very slow with 5000+ comments"
href="show_bug.cgi?id=76324">bug #76324</a>, but it's not! a duplicate of
this.
something is fixed / plastered / changed since that report, but something is
left or new.
calc produces massive performance issues when using plenty comments in a file
*and* after autosave.
see repro script below, system win7 pro SP1 (x64),
Steps to Reproduce:
1. idle computer
2. fresh start of calc
3. fill 100x100 cells with any data
4. open task manger
5. observe 'no significant cpu load' while moving the mouse around over the
sheet,
6. wait till first autosave of the file (you can set it to a short time for
that)
7. retry hovering around, observe 'no significant cpu load',
8. add comments to all theese cells (add comment to one and paste over the
oters),
9. see cpu-load peak on copying,
10. hover around with the mouse,
11. in some cases you see significant load, in other cases you have to wait for
the subsequent autosave, after that you'll likely see impressive cpu load just
from hovering around with the mouse ...
12. for recheck: save the file, restart calc, open the file, no cpu load on
hoverimg until the first autosave,
imho this load is unneccessary, and! negatively affecting the performance of
nearly any subsequent work or operation.
Actual Results:
unproductive cpu load on mousemoves after autosave of files with plenty
comments.
Expected Results:
cpu load on mousemoves similar to fresh load of file also after autosave has
taken place.
