This happens on other platforms too. As I understand, XeTeX has a
cache of fontnames that it uses to speed up font access, but the first
time a font is used, it will be quite slow; when a font cannot be
found, it goes to some effort to locate a copy on disk, but is
I could possibly see the utility of a flag to turn this off, but it
doesn't generally bother me too much :)
Incidentally, this slowdown is the primary reason that an
\IfFontExists macro isn't really feasible.
