Description rlk 2005-10-04 21:03:09 UTC 
I have a certain spreadsheet for which entering data is very slow (it takes
approximately 30 seconds to enter data into the spreadsheet on a 1 GHz PIII on
OOo 2.0.0rc).  For example, type 0<enter> into the freshly opened spreadsheet. 
On 1.1.5, it takes about 7 seconds (hence the regression).

Note: I *strongly* suggest opening this spreadsheet with automatic recalculation
turned off -- you may find that with automatic calculation turned on this
spreadsheet never successfully opens at all; it keeps recalculating and never
finishes before something or other starts it off again.

I don't see such a large difference. I get 5 seconds in 1.1.5, 11 seconds in
2.0. Most of the time is spent in the loop in ScBroadcastAreaSlot::AreaBroadcast
(used to be SvPtrArr, now std::set). This is also called once after loading, so
it affects loading performance, too.

This is a Dell Inspiron 8000 with 512 MB RAM running SUSE 9.1 with kernel
2.6.5-7.201-default.  I'm running KDE 3.4.2, which consumes quite a lot of
memory (and I did have other memory-intensive things present), but I didn't see
much if any paging activity.

What does AreaBroadcast do?  The name is somewhat suggestive, and I've seen
other performance issues involving screen redraw (in particular, sometimes it
redraws very slowly, sometimes redraws 2-3 times, and sometimes redraws
literally dozens of times.  Unfortunately I can't reproduce them reliably enough
to file a bug.

Accepted.

@rlk: AreaBroadcast broadcasts changes of cells in areas where other formulas
are listening to. Implementation changed with the numbers of rows increased to
64k. It is not related to screen redraws.
