Re: XeConTeXt bug report I: strange benchmark

[Yue Wang <yuleopen@gmail.com>]

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.
