hi every one.
i have a question when i want to open one document which has 960 pages
and about 9.5 mb with writer on windows xp.
when i try to open it, it needs exactly 1 hour and 45 minute to be
opened completely.
i gave my document to my sister for testing.
for her it took only 65 minute for openning.
whats the problem source and what should i do?
i think that my document is simple without images and graphical
thinks, but i am not shure.
because i use nvda screen reader and i dont know about graphics.
thanks for your answer and god bless you all.

Nasrin,

I'm no computer wizard, but I'm sure there are many reasons why a document would take much longer to load on a given computer. Different hardware could make a difference. Different amounts of memory. Different hard drive access speeds. Also, different operating systems will work differently. I run a computer with both Windows 10 and Ubuntu 14.04 on it and the Ubuntu side of things is noticeably faster than the Windows side.

That aside, I wonder if there's more in your file than you realize. I have a document of over 1,000 pages. The file size, however, is only about 857 kb, less than one tenth the size of your 960 page document. I can load my 1000+ page document in less than four seconds on a 2010 Sony Vaio laptop running Ubuntu 14.04. So, I think there's more going on inside your file than you might realize.

As a test, I would try saving it as a pure text file (.txt). See what the file size is then. Then you can reload it into LO, save it as a an .odt file and apply some reformatting. When you save it as a .txt file you will lose any footnotes or endnotes as well as any images, etc. but you'll at least be able to see what you've got in a stripped down format.

Good luck.

I am loading a 150 page with a lot of pictures of in total 140MB in 2 sec on my 5 year old Apple air

Suggest trying 2 looking at 2 things.
1. Clear Direct formatting.
2. If you have less than 20% of storage, clean up till you reach 30% and then Defrag.

Hope it helps.

Do you have lots of images in the document? That will certainly increase
the size of the file, but will also increase the loading and saving time. I
have a doc with 900 pages that loads and saves in about 15 seconds. I think
it has more than 1000 images. I moved all of them outside the odt file some
years ago which improved the performance, don't remember how much but alot.

Then, the xml code could need a cleanup of unused types etc which could
affect the performance. I have been looking for a cleaning program myself
but have not found one.

Last, the computer is of course of importance. Moving from an old laptop to
a new with SSD disk and fast CPU cut the loading and saving time to 50 %.

It is interesting that there are similarities with the recent discussion

What version of LO do you have.

hi again.
my system is little old.
my system property is:

System Properties

System:
Microsoft Windows XP
Professional
Version 2002
Service Pack 3

System:
Microsoft Windows XP

Version 2002
Service Pack 3
Computer:
Genuine Intel(R) CPU
T2250 @ 1.73GHz
1.73 GHz, 2.49 GB of RAM
Physical Address Extension
and my file is doc.
libreoffice is very fast and responsive in docx and odt file in
compare to doc files.
i tried many versions of libreoffice and the result was approximately the same.

Hi, I think it still took >1hr for the sister to open the document.
I don't use Nabble much but it is probably the only way for a new subscriber to look back over previous discussions.

Hi Nasrin,

That's all interesting but Steve asked what version of LibreOffice (LO) are you using. He also referred you to a discussion on a forum. I don't happen to like forums as well as mailing lists either but I suggest you take a look.

You said your sister opened the document faster. Is she using the same version of LO? Is her computer faster? Does it have more memory? You need to follow up on all these questions.

#10

hi.
yes.
my sister's computer is faster.
her cpu is higher and she uses windows 7.
yes, our libreoffice version is the same, version 4.3.7.2.
i tested this delay in many versions of libreoffice since version
4.3.0.4 and above.
i tested many versions.

whats the problem source and what should i do?

Determining the problem, without looking at the specific document is
extremely difficult.

Potential hardware issues are:
* Insufficient RAM:
^ How much RAM does your system have;
^ How much Free RAM does your system have;
^ RAM is failing;

* Hard drive(s) are failing;

* Inadequate space on the hard drives:
^ Microsoft claims that optimum disk drive performance occurs with 70%
of the hard drive free;

Potential Software, but not LibO issues:

* Resides on a non-local network drive;
* Quasi-incompatible USB connection;
* Anti-malware software that inspects every byte that is read, written,
or executed;

Potential document issues are: ^1
* Too many styles;
* Too many unused styles;
* Too much direct/manual formatting;
* Too many switches between styles;
* Too many calculations;
* Sub-optimal images;
* Poor layout of tables;
* Poor/bad formatting of frames;
* Poor/bad formatting of sections;
* How many documents does it link to;
* How many documents that it links to, that are not in their stated
location;
* How many documents it links to, that need to be first opened, then
some calculations run, then closed;

because I use nvda screen reader

I should have read the entire message first. :frowning:

Screen readers utilize a lot of system resources. The last time I tested
NVDA, it was almost as much of a resource hog as JAWS.
If anything in the hardware setup is about to fail, when a screen reader
is in use, system performance rapidly goes downhill.

Assuming your sister isn't using a screen reader, then most, if not all
of the 65:105 minute difference can be attributed to using a screen
reader. If she does use a screen reader, then the hardware on your
system is probably close to failing.

Regardless, 65 minutes to open a 9.5 MB document is abnormal.

^1: Whilst "too many" is vague, the optimum number depends upon one's
hardware. Some limits are built into LibO,
