[XeTeX] Xetex TexLife and fc-cache

It's not an intellectually satisfying solution, but could you not yourself
be the first (dummy) customer each day, offering up a file for PDF
conversion so that the initial slow processing happens only to you? The
real clients who come after that will then (if I understand your problem
correctly) get a fast(er) service.
If you want the service to run 24/7 (as would be normal for a web-based
service), it might be possible to automate this so that it kicks in at a
specific point (early) in the day. It would be interesting to know whether
it coincides with any daily archiving or updating at the server from which
your XeLaTeX distribution obtains its updates - e.g. whether this doesn't
work if you do it at 4 a.m. but it does if you do it at 7 a.m.

I see the same symptoms myself on a regular basis, but
not having clients to satisfy, it has never worried me.

You are not comparing like with like. XeTeX is a program,
based on the original TeX program from Donald Knuth, but
re-written and considerably extended, particularly in the
field of Unicode support and file handling. MikTeX is
a distribution, which contains TeX and many other programs,
probably including XeTeX ('though I have no first-hand
experience to support this latter statement). If you
do not need the power of XeTeX, and do not need (for
example), support for Unicode and for system fonts,
then TeX may be all that you need, and it will not have
that same startup delay; but the delay will be (more or
less) the same for any one given program (TeX, XeTeX,
LuaTeX, whatever) regardless of the distribution
(MikTeX, TeX Live, PC TeX, Y&Y TeX, whatever).
