When this document it is in use Libreofice 3.6 b3 start to consume lot of CPU....
even with Apache OpenOffice,
Reported it on other bug report, but the document when are opened use lot of CPU, 100%
This is the file, with russian characters...
It consume 70 to 100% CPU... all the time
It opens in reasonable time here (linux, 3.6rc1).
Scrolling of the loaded document is pretty low, but if you select it all and replace "GOST" font with something installed in your system (eg. FreeSans), then everything works reasonable after that.
I think it should be "enhancement" not "major".
Well, at least in the LO3.6 b3 even when changing the font to Liberation serif or sans it still use 100% of CPU, going to try with LO 3.6 RC
NOT reproducible with reporter's sample and "LibreOffice 220.127.116.11. German UI/Locale [Build-ID: 7122e39-92ed229-498d286-15e43b4-d70da21] on German WIN7 Home Premium (64bit). It seems that for may be 1 minute after having opened scrolling is a little jerky, but then everything works fine.
Same good result with with Server Installation of "LibreOffice 18.104.22.168 rc German UI/Locale [Build-ID: 73f9fb6] on German WIN7 Home Premium (64bit)
I read in Valek's Comment 1 that replacing Font "Ghost" improves handling, I can't confirm that for WIN.
I agree with you opinion that this looks like an enhancement request concerning performance as long as we do not have indications for a "real" bug.
Please describe you problem more precisely. In the Subject you write "when loading", what seems to say that you have difficulties to open the document. In the report you say simply having document opened costs nearby 100% CPU load.
- Write a meaningful Summary describing exactly what the problem is
– if possible contribute an instruction how to create a sample document
from the scratch
- add information
-- what EXACTLY is unexpected
-- concerning your PC (video card, ...)
-- concerning your OS (Version, Distribution, Language)
-- concerning your LibO version (with Build ID if it's not a public release)
and localization (UI language, Locale setting) where you observed the
problem the first time
–- Libo settings that might be related to your problems
(Auto-spellcheck? video hardware acceleration ...)
-- how you launch LibO and how you opened the sample document
–- If you can contribute an AOOo Issue that might be useful
-- everything else crossing your mind after you read linked texts
Hi guys, sorry for my bad description, I'm native spanish, well:
GNU/Linux Debian Unstable
LO 3.6 b3
LO 3.6 rc1
AMD RS780 AMD ATI Radeon HD3200
AMD Athlon X2 2.1GHZ
as you said I can confirm that the 100% CPU usage it's around 60 to 100% usage, after a while (1 or 2 minutes) it down to 10% usage...
There is no spellcheck on it.
I have it set at Spanish.
Well, the unexpected problem is why it consume lot of CPU if it is doing anything, not checking text, and if i have set it at liberation sans why it still using lot of CPU, why it is using CPU if it's using a know font?
Currently no bigger problems reproducible.

Have you changed something under "Tool - Options - LibreOffice - Memory" or have you changed "Tools - Options - LibreOffice - View; Graphics output" by any chance?
Hi, actually I have JAVA disabled, the options on memory tab are the described in the image http://subir.inodochile.net/images/1343707047.png
When I start JAVA i get a message:
Warning: failed to read path from javaldx

I can neither read nor understand Spanish, sorry ... :( But it seems, that the only options, we have in common, are the time (Eliminar de la memoria...) and the number of objects ... ;) It would be nice, if you could switch the UI language to English the next time, so that we QA guys and gals are able to understand, what you are talking about ... ;)
> When I start JAVA i get a message:

Oh, you should find many information about this error message, if you enter your distribution with its version/architecture and this error message in a search engine of your choice ... ;) I have found it in the past, when I got it ... ;)
Ok, Well, actually it kept using the 90% of CPU longer than 1 minute... using the LO 22.214.171.124 Going to install the last on 3.6.1 and i will provide more info about the CPU usage hahaha
Thomas, you are right, well, here is the screenshoot in english
can you try to check, if the problem is present in LO 4?
I opened the file, but the CPU usage was normal, scrolling is slow, but not causing high CPU usage.
Thank you, Matthias

after 3 minutoes it's still using 99% of CPU, using LO126.96.36.199
Created attachment 79283 [details]
Sample ODS file
Using LO 188.8.131.52 (Win7 Home Premium 32bit) I've experienced relatively normal opening the attached file.
But I found something abnormal while opening ODS file from Bug 54919 (I reattach that file here) -> took a very long time (very high cpu usage) to open
With the sample document provided by original reporter I cannot reproduce - the document opens quite fast (<10 seconds), no huge spike in CPU.
Marking as WFM -
With Comment 14 I suggest opening a new bug report to not mix things up (and only if the behavior is confirmed on 4.1 RC :)
LibreOffice Version 4.2 master

Where can I get the LO 4.2 package?
It's only a master build right now, not recommended at all for daily use. If you want to test it just once (again this is not recommended to keep as it's not stable)
