As far as I can judge the current version does not yet benefit from 
our discussion concerning the runs under OSX.

"ConTeXt  ver: 2005.03.02" (pragma site calls it 2005-02-03 [?] 15:19 
) doesn't include the changes that Patrick (no more "8 runs") found 
out:

sub FlushFiles
   { print TUO "%\n" . "% $Program / Files\n" . "%\n" ;
     foreach $File (sort keys %Files)
       { print TUO "% $File ($Files{$File})\n" }
     print TUO "%\n" ;
     $NOfFiles = keys %Files ;

"texutil.pl" is untouched.

I guess Hans is still verifying this perl hassle?

i changed it, not sure if i uploaded that version; the problem is that i'm now 
on too slow lines; next week i'm at

   eurotex 2005

i'll see if i can use the adsl line there for uploading.

Our discussion was finished 2005.03.03 so you might have the old
(buggy) version. Do you get the same amount of tex runs on both
systems?

texexec reports it

because we preload quite some encodings (maybe i will switch to delayed loading) 
we need more has space now; just set it to 70000+ in texmf.cnf

i wonder why these differences ...6 big fonts ?

do you load extra fonts?

can you make a small file that runs slower with the new versions?

sometimes these things are not related to context, but to your tex tree: the 
bigger the slower, as well as settings in texmf.cnf

Hmm. If you renamed the file for each run, then ignore that advice. I
don't think that would be it, then.

How do I count the number of runs? I mean, do I have to count, or does 
it tell me somewhere so that I can look it up?

The log files are lengthy, maybe the memory usage is of interest:

Run A:

12246 strings out of 64833
  221604 string characters out of 691267
  4755370 words of memory out of 6327867
  43583 multiletter control sequences out of 10000+50000
  21681 words of font info for 72 fonts, out of 2000000 for 2000
  104 hyphenation exceptions out of 1000
  58i,30n,104p,1295b,3134s stack positions out of 
1500i,500n,5000p,200000b,5000s
  6067 PDF objects out of 300000
  857 named destinations out of 131072
  956 words of extra memory for PDF output out of 65536


Run B:

Here is how much of TeX's memory you used:
  12374 strings out of 62208
  224135 string characters out of 638791
  4793260 words of memory out of 6324620
  46119 multiletter control sequences out of 10000+50000
  164026 words of font info for 78 fonts, out of 2000000 for 2000
  144 hyphenation exceptions out of 1000
  58i,30n,104p,1295b,3136s stack positions out of 
5000i,500n,6000p,200000b,40000s
PDF statistics:
  6073 PDF objects out of 300000
  857 named destinations out of 131072
  956 words of extra memory for PDF output out of 65536

The 'words of font info' (whatever it is) looks kind of strange to me.

My TeX source file is a single file with images. Most of the TeX-work 
is done for positioning
floats I think (figures, tables) and for creating backgrounds.

So I just renamed the TeX file for both runs into new file names, and 
upated TeX for the second run.
I can redo the experiment on a clone machine which hasn't been updated 
yet, but I don't
know whether "texutil --purgeall" will change anything. But if you tell 
me that it will, I'll give it a try.

how many runs?

normally context only becomes faster, so i wonder why it is so much slower

did you compare the logs?

Were both runs from the same point--were they "virgin" runs?
Did you precede the texexec command with a "texutil --purgeall" command,
for example?

No performance improvement under OS X with new beta?

[Matthias Weber]

Hello,

after the recent discussion of ConTeXt processing (some) files 4 times 
as often under OS X
than elsewhere, I decided to upgrade to the most recent beta and run a 
speed comparison
on notes I am writing. To my dismay, here are the results:

Old version:

ConTeXt  ver: 2004.11.23  fmt: 2004.12.16
TeXExec 5.2.3

total run time : 324 seconds


New version:

ConTeXt  ver: 2005.03.02  fmt: 2005.3.4
  total run time : 416 seconds

And I was hoping for a speed increase by a factor of 4 :(
(I renamed the TeX source for both runs)

Of course I am completely ignorant about the internals, but at least
I didn't expect that it would run slower.


Best wishes,

Matthias  (#7)
