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).
interesting. Earlier as the output was showing
mkiv lua stats > loaded patterns: en::1, load time: 0.000
mkiv lua stats > loaded fonts: 4 files: lucidabrightregular.otf,
lucidasansregular.otf, latinmodern-math.otf, lmroman10-regular.otf
you asked
so why not use lucida math fonts?
which is a valid question but nevertheless unsettling in that lmodern-regular
may nat have been called out. I fully understand the inclusion of a
latinmodern-math in it as a lucidamath was not previously available but I
ponder at the idea and involuntary implementation of having lmroman along the
pack. Why? If this is TeX doings, or misdoings (depending how one looks at it),
it clearly shows to me that TeX also restricts my freedom to use whatever font
I may deem necessary. Don't you think? You can probably disagree with me here,
or anyone from the TeX community can, but the roman last was imposed
deliberately upon. Someoe may also give a lengthy explanation but that would be
just hogwash in thee very end .
The fact that a file is loaded doesn't mean that it is used. In fact
there is some fallback loading going on because explaining when nothing
gets typeset or why \nullfont is used which results in missing chars
messages is a waste of time.
It has nothing to do with restrictions: tex will load any font you want
it. But for instance when you turn on some tracing the macro package can
load a font it needs. Indirectly you get what you ask for.
I bet you didn't explicitly ask for e.g. english hyphentation patterns
either but still got them, but tex will happily let you use polish ones
instead.
Of course the best remedy against any automatism is to just start with
initex and implement from scratch.
In the above case: just add \type {foo} and you might see another font
you didn't ask for / set up.
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).
Yeah. I guess.
I can also have
mkiv lua stats > loaded patterns: en::1, load time: 0.000
mkiv lua stats > loaded fonts: 3 files: lucidabrightmathsymbol.ttf,
lucidanewmathitalic.ttf, lucidabrightregular.otf
mkiv lua stats > font engine: otf 3.133, afm 1.513, tfm 1.000, 6 instances, 3
shared in backend, 1 common vectors, 2 common hashes, load time 16.723 seconds
but that loading time gets back at me as the culprit sweet reminder of not
using cmr then.
i won't comment because (i verified) that lucidabrightmathsymbol.ttf and
lucidanewmathitalic.ttf are illegal copies (if created on someones
machine from the typeone its all up to that user).
