Description pmike 2006-05-11 05:58:12 UTC 
A serious regression was introduced between m162 and m167 OOo builds.
m167 opens DOC files much slower: it's about two times slow for progress bar and
then bug (several minutes) delay. No memory allocs, no network activity during
that delay, only CPU load at 100%. This also happens when switching between
edit/view modes.

No attachments are required, this applies to all DOC files.

Please consider this as serious regression (maybe P2), since performance is
crucial for OOo.

I cannot see this. I opened a 1.7 Meg large .doc file with 680m168 build and it
needed exactly the same time as in OO 2.0.2. Please check your installation.

Closed.
Comment 3 pmike 2006-05-12 09:02:19 UTC 
Well, I've updated to m168. Same problem.
Update: not all DOCs open slowly. Some of them opens fast, some slow.

How can I upload large (5.5 Mb original, 2.2 Mb if packed with 7-zip) DOC?
There is 1Mb limit on regular uploads.
OOo m167 and m168 simply hangs on opening this file.
But OOo 2.0.2 opens it in few seconds.

We have also discovered a heavy regression in performance opening a special kind
of Word documents. Did you also experience that it was good in m165/m166 build?
The performance loss seems to affect documents containing a special kind of
numberings.

MRU->OD: the attached document need extremely long to open (not the import, the
formatting process takes its time). Also with odt documents this can be seen.
I will also attach a second odt where copy and paste will lead to this problem.

Comment 9 Oliver-Rainer Wittmann 2006-05-12 11:56:07 UTC 
fixed in cws swqbf65 - changed file:
/sw/source/core/SwNumberTree/SwNumberTree.cxx, 1.5.12.1

defect cause:
method <SwNumberTreeNode::ValidateContinuous(..)> is called endless recursively.
Comment 10 Oliver-Rainer Wittmann 2006-05-12 12:36:30 UTC 
OD->MRU: Checked in internal installation set of cws swqbf65 - please verify.
