sure, why should it, you want lucida so better quit with an error than

Font loading and processing time can be mosty neglected so these 16
seconds come from something else, maybe there are ways to trace file
access. Another possibility is that your fonts are not cached in which
case every run will involve parsing the otf / ttf and producing whatever
resources needed (normally cached).
I was actually thinking to ask you about that, and by falling back to cmr math
font that perhaps would expedite loading time along the way.
These fonts are small (only huge cjk fonts with tens of thousands of
glyphs or fonts with hundreds of accumulated features might have some
impact but even then not in the final embedding stage).
Whan talking fonts, enabling for instance expansion (hz) and protusion
might increase runtime a little. In practice, enabling for instance
synctex has a bigger imnpacts on performance than handling fonts.
