Version|4.0.4.2 release |3.6.1.2 release

--- Comment #19 from tommy27  ---
more extensive performance tests about loading time of:
attachment 90994 [details] 
attachment 91339 [details] 


3.5.7.2 and 3.6.0.4

7 seconds
3 seconds


3.6.1.2 -> 3.6.3.2

11 seconds
4 seconds


3.6.4.3

1 minute and 40 seconds
12 seconds

...
3.6.7.2
...
1 minute and 35 seconds
13 seconds

...
4.1.5.2
...
5 minutes
36 seconds

...
5.2.4.2
...
46 seconds
18 seconds

...
5.4.0.0.alpha0 (Jan 2 2017)
...
44 seconds
14 seconds


as you may see, loading time was very fast in LibO 3.6.0 for both files (7 and
3 seconds each), than had a small performance drop in 3.6.1 to 3.6.3 (11 and 5
seconds) and a more consistent performance regression in 3.6.4 and 3.6.7 (1
minute and 40 seconds and 13 seconds).

things became even worse in 4.1.5 which showed incredibly slow loading times (5
minutes and 36 seconds) but improved in 5.2.4 and 5.4.0.0 Dev.

so things are better now but still suboptimal:

attachment 90994 [details] 
3.6.0.4 ->  7 seconds
5.4.0.0 -> 44 seconds

attachment 91339 [details] 
3.6.0.4 ->  4 seconds
5.4.0.0 -> 14 seconds

retested under Win8.1 x64 with SSD disk.

these are loading times of attachment 90994 and attachment 91339 

...
3.6.7.2
...
1 minute and 35 seconds
13 seconds

...
4.1.5.2
5 minutes
36 seconds

...
5.2.4.2
46 seconds
18 seconds

...

this proves that there are 2 separate issues regarding those 2 attachements.

I would call RESOLVED WORKSFORME the loading of attachment 90994 that is
considerably faster in 5.2.4.2 

the loading of attachment 91339 is still slower than 3.6.7.2 but much better
than previous releases.

With Version: 5.2.4.2 (x64)
Build ID: 3d5603e1122f0f102b62521720ab13a38a4e0eb0
CPU Threads: 2; OS Version: Windows 6.19; UI Render: default; 
Locale: en-US (en_US); Calc: single

the first example loads in about 20-25 secs and the second one in about 10
secs.
Could be faster (?!), but it's certainly not 5-7 mins anymore.

Unsure if this is sufficient, but according to a previous comment this couldn't
in any case be reproduced in Linux.

The following is a callgrind log from loading the second smaller document on
OSX, where I can reproduce the issue on 4.4 master (external link due to large
size):

Possibly also of interest: For the second file (IDPZK_MODUL_2.doc),

Save - Reload - Issue still present (so whatever the problematic formatting
is, it appears to survive a round trip through .doc)

Save as ODT - Reload - Save as .doc - Reload - Issue still present (ditto
round trip through ODT, although the issue does not occur when loading from
ODT)

Set all text to one language - Save - Reload - Issue no longer present



Looking at the content.xml of the file as an ODT,

And so on. There appear to be long paragraphs of text where the language flips
to EN and back between every word. Whether or not it's specifically language,
it seems plausible that the slow loading speed may have something to do with
this property dance.



Setting the language doesn't seem to do anything to the larger document, so
there may be something else going on there.

--- Comment #15 from Matthew Francis fdb...@neosheffield.co.uk ---
Results of similar analysis of the larger document:

Roundtrip by Save in LO (as .doc or .docx) - Reopen - Issue not present

Roundtrip by Open in Word (Mac, 2011) - Save as .docx - Reopen in Word -
Save as .doc - Reopen in LO - Issue still present


Thus, comparing the OOXML saved by LO and Word to find the difference, it is
quickly apparent that where LO writes in document.xml:

w:p
w:pPr
w:pStyle w:val=Normal/
w:spacing w:lineRule=auto w:line=360/
/w:pPr
w:r
w:rPr
w:color w:val=00/
w:sz w:val=28/
w:szCs w:val=28/
w:lang w:val=uk-UA/
/w:rPr
w:tРoздiл 1. Прaвoвi зaсaди тa мeхaнiзми мирoтвoрчoї
дiяльнoстi ЛAД..12/w:t
/w:r
/w:p

The same line of text written by Word instead goes:

w:p w:rsidR=000137C5 w:rsidRPr=004F22BB w:rsidRDefault=000137C5
w:rsidP=000137C5
w:pPr
w:spacing w:line=360 w:lineRule=auto/
w:rPr
w:color w:val=00/
w:sz w:val=28/
w:szCs w:val=28/
w:lang w:val=uk-UA/
/w:rPr
/w:pPr
w:r w:rsidRPr=004F22BB
w:rPr
w:color w:val=00/
w:sz w:val=28/
w:szCs w:val=28/
w:lang w:val=uk-UA/
/w:rPr
w:tР/w:t
/w:r
w:r w:rsidR=0004393B w:rsidRPr=004F22BB
w:rPr
w:color w:val=00/
w:sz w:val=28/
w:szCs w:val=28/
w:lang w:val=uk-UA/
/w:rPr
w:to/w:t
/w:r
w:r w:rsidRPr=004F22BB
w:rPr

...

...for a total of 42 w:r for one line of text, each with one or only a few
characters in it. LO appears to be merging these segments on load, while Word
does not.

In total, in the version of the OOXML saved by LO there are 1102 w:r, while
in the Word version there are 76028.

As with all of these we need a callgrind trace of this opening under Linux with
a build with debugging symbols installed thus:

export OOO_EXIT_POST_STARTUP=1
export OOO_DISABLE_RECOVERY=1
valgrind --tool=callgrind --simulate-cache=yes --dump-instr=yes ./soffice.bin
--splash-pipe=0 my-test-file.doc

zip and provide the callgrind.12345.txt file - hopefully the slowness jumps out
of that =)

Thanks

Version|4.3.0.0.alpha0+ Master  |4.0.4.2 release

--- Comment #10 from tommy27 ba...@quipo.it ---
tested attachment 91339 with older releases under Win7x64

LibO 3.3.3 -- 3.6.7 takes 15 seconds to open (which is suboptimal too)

LibO 4.0.4 -- 4.1.5 take 32 seconds to open

probably a performamce regression started in the 4.0.x development

(*) times to load may vary according to the power of the PC that was used.
mine was a 5 years old laptop.

I add Micheal Meeks to CC list since he's one of the performance experts.

 I can confirm: the first doc is loading on my win7 64bit i7, but takes 7min
 to open with LibO4.1.3.2)

Ouch -- yes, sounds like a pretty classic performance issue.

Dennis/Witalik - Could you please test with older versions (4.0, 3.6, 3.5,
etc..) and see if the performance problems are a regression?

Thanks!

So as it seems, that there is already some work done on the performance. But in
my eyes not enough - at least it just takes too long.

Version: 4.2.0.1

Opening from scratch: 75 sec.
(same with 4.2  4.3)

Opening a document in doc format needs a conversion. 
The same document saved in odt format opens in a second on my platform.
