So, unless I missed something, it looks like pattern processing with LuaTeX
takes almost twice the times is takes with pdfTeX. Not sure if it is related to
the generation of the fall-back states you mention or some other change in the
internal code.
(1) the internal code is different
(2) the machinery is utf (large numbers internally)
(3) patterns are utf
in general the luatex machinery is slower than pdftex (upto two times,
depending on what you do) which is mostly due to the fact that pdftex is
8 bit
in context mkii we are using utf encoded patterns and there loading
patterns in pdftex is definitely slower than in xetex and luatex simply
because in pdftex one has to parse
(also, it depends on the language, for instance, russian has large slow
loading patterns)
