Description Stephan Bergmann 2004-11-12 12:23:48 UTC 
As a performance example, starting and then automatically terminating SRC680m60
unxlngi6.pro soffice.bin -invisible on one machine (sb-1) takes 3 sec, of which
.7 sec are spent in the dlopen of libsfx680li.so (which includes the recursive
dlopen of libxo680li.so).

Comment 2 matthias.huetsch 2004-11-14 17:02:47 UTC 
Adding dependency to issue 20269 (startup performance), inheriting it's priority
(P2).
Comment 3 matthias.huetsch 2004-11-14 17:03:42 UTC 
Adding myself to CC...
Comment 4 Stephan Bergmann 2004-11-16 16:13:14 UTC 
After symbol reduction for libsfx680li.so and libxo680li.so, the above scenario
takes .5 sec less.
Comment 5 Stephan Bergmann 2004-11-16 16:25:35 UTC 
Fixing this issue introduced slight changes in three places where XML files are
processed.  These changes can be tested for regressions as follows:

1  Changes in starmath/source/mathml.cxx:
Save and load documents in "Open Office Formula (*.oof)" format.  Also try to
exchange such documents with older OOo instances (without this issue
integrated), in both directions.

2  Changes in sfx2/source/doc/xmlversion.cxx:
Modify the version list of a document ("File - Versions...").  Also try to
exchange documents with version lists with older OOo instances (without this
issue integraged), in both directions.  This feature will only work once issue
37232 is fixed.

3  Changes in svx/source/xml/xmlxtimp.cxx and svx/source/xml/xmlxtexp.cxx:
Save and load gradients list .sog files (e.g., in a text document, insert a
shape, and via context menu "Area... - Gradients" use the "Load Gradients List"
and "Save Gradients List" buttons).  Also, try to exchange .sog files with older
OOo instances (without this issue integrated), in both directions.  This feature
will only work once issue 32542 is fixed, on SRC680m62.

Verified in CWS sb25. Checked by JA (performance), WG (Gradients) and MRU
(versioning and Math).
JA's results:
nm -D --defined libsfx680li.so |wc -l
2782 [10185]
nm -D --defined libxo680li.so |wc -l
1320 [11495]

Checked integration in 680m74.
