Not the X-server, the font server.
If the font is not yet in the system font cache it must be
processed and stored.  This can be slow, so the first time
a font is requested you may get the error message about
"slow font initialization".  After that the font is in the
cache so access is fast.  On my systems the font cache
is persistent so you would generally only see such a message
if you have not logged in or run gnuplot for a long time.
I do not know how persistent the cache is under Windows.

If it only happens once per session I don't think it an an error.
The font server really is slow on the first access and gnuplot
is telling you that.  The same thing would happen for any other
program that requested a font for the first time, but it might
not print a message.
