Re: XeConTeXt bug report I: strange benchmark

[Yue Wang <yuleopen@gmail.com>]

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.
