Re: [NTG-context] XeConTeXt bug report I: strange benchmark

12 May 2009

      sorry the the context sample and latex sample are not equivalent
(note the \par).

So I test again:
\starttypescript[serif] [myzhfont]
 \definefontsynonym [Serif]           [file:SimSun]
 \definefontsynonym [SerifBold]       [file:SimSun]
 \definefontsynonym [SerifItalic]     [file:SimSun]
 \definefontsynonym [SerifBoldItalic] [file:SimSun]
\stoptypescript

\starttypescript[sans] [myzhfont]
 \definefontsynonym [Sans]           [file:SimSun]
 \definefontsynonym [SansBold]       [file:SimSun]
 \definefontsynonym [SansItalic]     [file:SimSun]
 \definefontsynonym [SansBoldItalic] [file:SimSun]
\stoptypescript

\starttypescript[mono] [myzhfont]
 \definefontsynonym [Mono]           [file:SimSun]
 \definefontsynonym [MonoBold]       [file:SimSun]
 \definefontsynonym [MonoItalic]     [file:SimSun]
 \definefontsynonym [MonoBoldItalic] [file:SimSun]
\stoptypescript

\definetypeface [myzhfont] [rm] [serif][myzhfont]   [default]
\definetypeface [myzhfont] [ss] [sans] [myzhfont]   [default]
\definetypeface [myzhfont] [tt] [mono] [myzhfont]   [default]

\def\a{\myzhfont}

\dorecurse{10000}{{hello {\a 你好}}\par}

\bye

XeConTeXt uses 45.502 seconds, while XeLaTeX uses 3 seconds.

2009/5/12 Yue Wang :
...
here is the xelatex result given by a chinese user:
\documentclass{minimal}
\usepackage{xeCJK}
\setCJKfamilyfont{song}{SimSun}
\begin{document}
{hello {\CJKfamily{song}你好}}\par % 10000 lines
\end{document}
got 209 pages, three seconds to run.
note he is switching  families 20000 times. (\family{foo} in latex ==
\switchbodyfont[foo] in context)

Hi,
Sum up:
define a font usng typescripts takes 64.797 seconds.
define a font like \definefont[a][file:SimSun.ttf] takes 55.548 seconds
define a font like \definefont[a][file:SimSun] takes 4.329 seconds
define a font like \font\a="[simsun]" takes 1.812 seconds
Jonathan and Jin-Hwan, sorry for the noise. I am now sure that it is a
context bug, not xetex's.
and
...
update: change the second example, remove the ".otf" suffix , and
texexec --xtx gives:
TeXExec | runtime: 5.766
Obviously, this is a parsing bug in ConTeXt.
context is not parsing for .otf or .ttf and has no reason for it either
