merging pdf (repost)

[scarso luigi]

Hello, I use this code to merge file1.pdf, file2.pdf, file3.pdf  in
file4.pdf

% format=english
\definepapersize[A3large][width=320mm,height=450mm,offset=0pt]
\setuppapersize[A3,landscape][A3large,landscape]
\setuplayout
    [backspace=0pt,marking=on,
     height=middle,width=middle,location=middle,
     topspace=0pt,
     header=0pt,
     footer=0pt]
\starttext';

\insertpages[file1.pdf][width=0pt]
\insertpages[file2.pdf][width=0pt]
\insertpages[file3.pdf][width=0pt]
\stoptext

where 
file1 is    481 031 bytes
file2 is  1 277 167 bytes and
file3 is     43 574 bytes. I expected ~2 Mbytes for file4.pdf but 
file4 is 10 601 693 bytes, ie ~five times the size expected.
Why ?

Thanks in advance
luigi

PS.
I have a context distribution that is 1 year old, but i can't actually
upgrade it (well, if I must do it, I will do !)

maybe an not supported compression scheme?

in a couple of weeks a new tex live is out, so a newer pdftex (xpdf lib) 
may have solvedthe problem.

Thanks Hans for the answer.

I made another try with
file1.tex:

\setuppapersize[A3,landscape][A3,landscape]
\starttext
\dorecurse{1500}{\input tufte \par \input knuth \par}
\stoptext


and merge.tex:

\definepapersize[A3large][width=320mm,height=450mm,offset=0pt]
\setuppapersize[A3,landscape][A3,landscape]
\setuplayout
    [backspace=0pt,marking=on,
     height=middle,width=middle,location=middle,
     topspace=0pt,
     header=0pt,
     footer=0pt]
\starttext
\insertpages[file1.pdf][width=0pt]
\stoptext

The results are:
 799537 ago  7 17:55 file1.pdf
1515097 ago  7 17:56 merge.pdf

Also pdffonts file1.pdf give
name                                 type         emb sub uni object ID
------------------------------------ ------------ --- --- --- ---------
EGNYTD+CMR12                         Type 1       yes yes no       6  0


but  pdffonts merge.pdf give
name                                 type         emb sub uni object ID
------------------------------------ ------------ --- --- --- ---------
AGPRLI+CMSS8                         Type 1       yes yes no      15  0
MGUYCG+CMR12                         Type 1       yes yes no       7  0
:
:
MGUYCG+CMR12                         Type 1       yes yes no       7  0


ie the  line
MGUYCG+CMR12                         Type 1       yes yes no       7  0
 is repeated 408 (yes, four hundred) times .

Do I mess with pdftex.cfg or some *.map files ?

here i get:

   805,366 test.pdf
1,053,739 test1.pdf

so .. what version of pdftex are you running

normally pdftex combines fonts data (esp the glyph code) that it knows; 
some overhead is to be expected form the rather verbose resource related code

hm, then update to 1.0 or higher

Re: merging pdf

Good news, 
it seem to work after updating to 1.11
( This is pdfTeXk, Version 3.141592-1.11a (Web2C 7.5.2))

I get
  797,077 test.pdf
1,078,539 test1.pdf
and your test was
  805,366 test.pdf
1,053,739 test1.pdf 

(Does it depend from pdftex version ?)

Previous merging is also good: I have now  1,767,252 bytes
(it was ~10Mbytes)

Many thanks Hans

i used 1.10a for that test (1.11 is in my test suite) and there are indeed 
differences between pdftex versions: the latest greatest has a couple of 
optimizations, even more accuracy, a few more features etc. Also, the xpdf 
lib plays a role in producing code.

(version 1+ avoids redundant copies of objects when including multiple 
pages from a file)
