Hm, all this is a little cloak-and-dagger. 
It seems that reporter's sample indicates a bunch of possible problems, real
bugs, possibilities to improve LibO, currently I believe we have to separate
several problems, may be to submit several bugs.


Software           Document First      Furter      Remark
                   import   Picture    Pictures
-------------------------------------------------------------------------
LibO 3.5.5.3:      120s     10s        several s   [1] [2] [4]
LibO 3.3.3         150s     10s        several s   [1] [2] [4]
LibO 3.7.0.alpha+  120      10s        several s   [1] [2] [4] [5] [6] 
OOo 3.1.1          130s     20s        several s   [1] [2] [4]
OOo 1.1.4:          45s      1s         0s         [3]
MS Word Viewer:      3s      2s         2s         [1] [2]

Remarks:
[1] After Document has been opened only pictures in focus will be loaded. 
[2] When a new picture comes into focus it takes another 5s or Longer until
picture will appear. One reason might be that some of the pictures on the
server are created only for request, as I see from "w=424&h=640" in the picture
URL. So the "document open" never becomes ready

[3] Document completely ready immediately, all pictures are aht their place and
visible immediately when scrolling reaches it
[4] Import time of 120s for a 35 pages document seems to be rather long. After
having saved the document as .odt reopening will only take a second or so, also
with other versions than the one with what the document has been saved.
[5] Pictures nearby end of document seem to take much longer to become visible
when in focus than pictures at the beginning _(but I did not test this
systematically)
[6] PDF Export immediately after .doc has been opened takes several minutes
(may be because pictures still have to be loaded one by one), also for .odt
created from .doc. I only tested this for Master, but expect the same results
for other Versions.

Remaining Questions:
a) is VBA code in the documents involved into the problems we see?

Possible Bugs / core Problems
A) General Import Time too long, OOo 1.1.4 is the minimum goal
B) Pictures should be loaded immediately and completely immediately when 
   document has been opened

I will have to think about these results, But I beleive we shoud separate this
bug into 2 ones: 1. the picture download problem and 2. the too long import
time until document becomes visible.

What do you think?
