Description Marc Sabatella 2011-09-11 17:24:23 UTC
Created attachment 51061 [details]
the document export from google

I did a search and found a few people with sort of slightly slow load/save complains - 10-20 seconds, that sort of thing - but I'm seeing save times in excess of 10 *minutes* on a 90 page document.  The document was created in Google Docs and exported to ODT format from there.  It contains a couple of Drawing objects (created within Google Docs) that are apparently converted to a series of bitmap images in the ODT file.  The file takes around a minute to load, during which time the progress bar goes from 0% to 100% about a dozen times.  After making any small change to the file and trying to save, it takes around ten *minutes* to save, with the progress bar going from 0% to 100% just once.  A subsequent load and save of the same file, however, takes only ten *seconds* or so.  This is using LibreOffice 3.4.3, build 302.

The attached file reproduces this for me.  Make a one-character edit then do a save (or save as), takes ten minutes.  Close (this may also be slow), reopen, one-character edit, save - takes ten seconds.

[Reproducible] with "LibreOffice 3.4.3 RC2 - WIN7 Home Premium (64bit) German UI [OOO340m1 (Build:302)]", saving the document under new name without changes in contents takes several minutes with excessive CPU load. Same problem with with Server installation of Master "LibO-dev 3.5.0 – WIN7 Home Premium (64bit) English UI [(Build ID:  d3d1481-3f8994a-2ba0a9f)]".

No problem with OOo 3.1.1.

No problem with "LibreOffice Portable 3.3.3  - WIN7  Home Premium (64bit) German UI [OOO330m19 (Build:301  Tag 3.3.3.1)]", so this seems to be a regression.

I would really like to know what those lots of progress bar reappearances during fileopen might mean.

NOT reproduced with

LO 3.4.3 OOO340m1 (Build:302)
Ubuntu 10.04.3 x86
Linux 2.6.32-33-generic Russian UI

Really Windows specific.
Comment 3 Arnaud Diederen 2011-11-16 23:48:54 UTC
I could reproduce this on an
 * ACER Aspire 4625
 * Ubuntu 11; unmodified, unpatched (except for the ATI drivers)
    - Linux hilbert 3.0.0-12-generic #20-Ubuntu SMP Fri Oct 7 14:56:25 UTC 2011 x86_64 x86_64 x86_64 GNU/Linux
 * 4GB RAM
 * Plenty hd space (126GB):  /dev/sda5             141G  8,4G  126G   7% /
 * LO 3.4.3 (build 302)
 * very few programs open
 
The file attached by Marc takes more than a minute to save.
Therefore, I don't believe it is windows specific.

Since all new unconfirmed bugs start in state UNCONFIRMED now and old unconfirmed bugs were moved to NEEDINFO with a explanatory comment, all bugs promoted above those bug states to NEW and later are automatically confirmed making the CONFIRMED whiteboard status redundant. Thus it will be removed.
Comment 5 ign_christian 2013-06-27 04:47:31 UTC
Not reproducible on LO 4.0.4.2 (Win7 32bit).

Only takes less than a minute to load or save, with 'only' Pentium U4100 1.3 GHz & 2 GB RAM.
