Hi:

 lua garbage collection on xp is somehow quite slow, when i switched to
 vista, the luatex test files (mk) that took forever on xp, ran smoothly
 on vista
OK. Today I got a copy of windows vista, so I installed it on the same
machine, and test the same tex file.

how much memory? (vista needs some 2 gig at least)

Re: [NTG-context] Can we make font loading much faster?

2008-09-14 Thread Yue Wang
I usually compose short documents (paper, homework, report etc.) which
usually runs 8-10 pages.
There will be considerable difference between traditional TeX (CJK for
LaTeX, or pdftex MKII using subfonts) and MKIV.
That means, every MKIV Chinese document I compile will spend 10
seconds loading the fonts and extra 5 seconds for compiling the
actual document.

For longer documents (more than 100 pages), I seldom compile them all.
ConTeXt user usually split the book into components. I compiled each
component (usually 10 pages) until I am satisfy in all components,
then I will compile the whole book. So, efficient on small document is
very important.

[NTG-context] Can we make font loading much faster?

2008-09-12 Thread Yue Wang
Hi:

The following cases all use second run of context. So there is no font
cache time. I use a new installed Windows XP SP3 on a Core 2 Duo
1.68GHz with 1GB mem machine. Only TeXWorks and ConTeXt are installed
and running on the machine. I close all pre-installed software (like
MSN, IE, etc.) and leave all extra memory for LuaTeX.

Only 3 big chinese font, AdobeSongStd-Light, AdobeHeitiStd-Regular,
AdobeKaitiStd-Regular are loaded. However, different approaches have
different runtime, here, two cases are tested (zhfonts is attached in
the mail):

In a typical chinese science book, usually 4 to 10 chinese
truetype/opentype font are used. Magazines might use twenty or more.
So if we want to use the standard way (use chinese font as body font,
use virtual fonts mechanism to mix the font with latin fonts, use
different alternatives for single chinese font)
as the zhfonts.tex is presented, the running time here is usually
intolerable (more than 3 minutes' loading time with very simple text
for three fonts).

A simple XeLaTeX file with three font embeding using XeCJK or
zhspacing for interchartoken font switching  usually runs less than 8
seconds. In this case, all the family (rm, ss, tt) parts (like bf, it,
etc) in NFSS are defined.

So, I think there should be a way to improve the font loading
procedure. Maybe we had made deep copy to every fontsynonym defined
here which made the loading time terribly long? Are there some way to
mirror all the unchanged part of a new loading font B from a loaded
time A and only leave the modified table when A and B points to same
physical font? Thanks.

the reason for this is that including the files in the pdf files takes 
long; we suspect that there might be a memory issue there (not freed) so 
that on your system you end up with swapping (it is on the agenda to 
look into this)

 In a typical chinese science book, usually 4 to 10 chinese
 truetype/opentype font are used. Magazines might use twenty or more.
 So if we want to use the standard way (use chinese font as body font,
 use virtual fonts mechanism to mix the font with latin fonts, use
 different alternatives for single chinese font)

it's not virtual fonts at all, these fonts are used in parallel and 
fallbacks are applied by node list parsing; this also means that the 
fallback fonts have feature support (independent of the main font)

 as the zhfonts.tex is presented, the running time here is usually
 intolerable (more than 3 minutes' loading time with very simple text
 for three fonts).
 
 A simple XeLaTeX file with three font embeding using XeCJK or
 zhspacing for interchartoken font switching  usually runs less than 8

 physical font? Thanks.

at the lua end there is already a lot of sharing going on but eventually 
the font has to be fed into tex itself where there is no such sharing

anyhow, performance might improve over time

 Can you give me a hint to find what's wrong here?
 I use the minimals GUI installer, and after installation,
 I copy the fonts to texmf-fonts/fonts/opentype.

when you set fonts.trace=true you will see that many fonts are defined

at some point we might make this an option: no \tfa..d etc at all since
in styles one might prefer to use hard coded fonts for titles or just
switch the bodyfont (is relatively fast with typefaces); the reason for
these extra sizes are convenience and speed (at least that was the case
10 years ago)

for the moment, a way out of your problem is (please wikify this)

  \synchronizemathfontsfalse

or less intrusive

  \let\synchronizetext\relax

you should keep in mind that the context font mechanisms evolved over
time and that they support rather complex mixted usage of fonts (i.e.
mixing complete sets of different typefaces and such); this comes at a
price (normally goes unnoticed)

Re: [NTG-context] Can we make font loading much faster?

2008-09-12 Thread Mohamed Bana
I've also been wondering why LuaTeX is considerably slower than XeTeX.  Has
anyone been doing any research into LuaJIT?

(1) luajit is non portable (not on all architectures) so for the moment 
it's no option

(2) luatex will always be slower, because we do many things in lua ... 
it's the price of flexibility and opening up

(3) although we do our best to speed up luatex and mkiv as much as 
possible it's not our intention to compete in speed with pdftex (only 
type 1, frozen funtionality, etc) and xetex (depencency of libraries, 
closed engine, etc)

(4) at some point (and there are already a few areas where this si true) 
  luatex/mkiv will be faster than a traditional tex engine where all 
happens in macros (or is hadcodes)

(5) machines become faster and mem cheaper

(6) you're free to use the engine you like most

[our benchmark docs are not that much slower than for instance pdftex 
esp when one consideres the extra functionality available]

Just a very short remark: I'm testing my presentation stuff  
extensively these days, and there's a lot of metapost graphics  
involved. mkiv is amazingly fast, while both mkii and xetex take very  
long to compile my test files (and clutter the directory with all the  
intermediate files). Font loading tends to be long at first run and  
quite efficient thereafter.

Hi:

  \synchronizemathfontsfalse

Woo... It is much faster! Thanks for your magic.

 你好 {\it 你好} {\bf 你好} use 24.750s,
 你好  use 11.766s,
 Hello World use 6.438s.

I will wikify this together with a short introduction for chinese
typesetting in MKIV.


 lua garbage collection on xp is somehow quite slow, when i switched to
 vista, the luatex test files (mk) that took forever on xp, ran smoothly
 on vista

@@ buying a copy of vista is not on my budget too expansive.
I will test this on GNU/Linux later.

You are right, Hans. This is a XP specific problem.
(Of course, 15.854s runtime is still a bit too long, but that's tolerable)
