Hi, Hans and Jonathan:
I made some testing samples in ConTeXt to test XeTeX. but the result
is quite strange. All benchmark are get from the second run:
Sample 1:
\definefont[a][file:SimSun]
\starttext
\dorecurse{10000}{ hello {\a 你好}}
\stoptext
And here is the result:
XeTeX: TeXExec | runtime: 7.25
LuaTeX: MTXrun | total runtime: 6.719
This is considerablly ok. So we can say that the font switching is pretty fast.
Sample 2:
\definefont[a][file:AdobeSongStd-Light.otf]
\starttext
\dorecurse{10000}{ hello {\a 你好}}
\stoptext
XeTeX: TeXExec | runtime: 63.65
LuaTeX: MTXrun | total runtime: 8.156
Here I only change the font from SimSun to Adobe Song (the two fonts
are almost at the same sice [~10M]).
But the xetex result is very differt from the previous run. it
consumes one minute to compile the file.
Sample 3:
\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}
\starttext
\dorecurse{10000}{ hello {\a 你好}}
\stoptext
XeTeX: TeXExec | runtime: 64.797
LuaTeX: MTXrun | total runtime: 10.797
Here we use SimSun since in the first sample xetex can load simsun quite fast.
However, in this time we define a typescript, and make all the styles
fall into SimSun.
Now xetex behaves quite strangely: it uses one minutes to compile this
single document...
So my question is
- why loading otf is so slow?
- is this a bug in context or in xetex? can it be fixed?
- how can we make sample 3 (using typescript) run faster?
Thanks.
Yue Wang
