Description Germano Massullo 2010-07-01 12:53:53 EDT
When I use the math formula, the writer performances reduce drastically and 
everything in the writer is so slow!
I attach the document I am writing in.
The OpenOffice version is 3.2.0 with Fedora 13, and I don't know how is the 
version of writer I have to select here.

I have this problem on both my pc.

I've previously reported this bug on Openoffice.org bug report website, but it seems that the problem is only on Fedora packages.

They're just using the CrazyDistroDefense http://wiki.services.openoffice.org/wiki/CrazyDistroDefense

Its no speed demon on this document I'll admit, but what specifically was sufficiently slow to drive you to report this. The redraw of equations when scrolling down the page ? Performance issues are hard to fix to everyone satisfaction when it can be uncertain as to what needs to be improved. Can you assign some objective number to something exact, e.g. "it takes X seconds to do Y"

Here's some variables to play with to see if they make a difference.

Comment 4 Germano Massullo 2010-07-01 16:01:15 EDT
Before assigning some objective number to actions like "it takes X seconds to do
Y" I would try before the two settings you suggested me.
Where can I insert them? In which specific config file?
Comment 5 Caolan McNamara 2010-07-01 16:13:18 EDT
shutdown office, launch a terminal e.g. gnome-terminal and just cut and paste

and then
to try out that environmental variable on its own.
Comment 6 Germano Massullo 2010-07-01 17:16:51 EDT
Done with 
Nothing changes.
It takes at least 1-2 seconds to show some parts of the document. I have a newer version of the document with lot of new formulas
Comment 7 Germano Massullo 2010-09-05 16:40:59 EDT
Will this bug fixed in Fedora 14?
Comment 8 Germano Massullo 2010-09-05 17:05:39 EDT
Actually I am forced to use the RPM of OpenOffice 3.2.1 provided by Oracle in openoffice.org website. That version seems to work on my desktop pc and has NOT slow performances on formulas, I can scroll very smothly without problems.
Comment 9 Caolan McNamara 2010-09-06 04:04:15 EDT
Well, if vanilla 3.2.1 is not slow but the Fedora one is, then it is presumably the fontconfig work which is causing it (though I don't see the slowdown myself) in which case this work is integrated into 3.3.0 as in F-14 and in vanilla so either the vanilla 3.3.X will be just as slow as the fedora one, or the extra optimizations added during 3.3.X will fix the problem.

i.e. either way I expect F-14 3.3.0 to be the same as vanilla 3.3.0 speedwise
Comment 10 Caolan McNamara 2010-10-19 11:13:06 EDT
Must be the fontconfig work. Which got merged into the "vanilla" OpenOffice.org as well now, so both render the same way from 3.3 onwards
