much overhead is related to things like setting up math, synchronizing
encodings, mappings, (and hz, protruding if enabled) .. keep in mind
that we're talking of font systems, not one font

it all depends on what functionality is needed (take pagebody
construction, which in plain is hardly present, backgrounds, color, etc
etc) and in the case of xml it also depends on what 'defineXML' commands
are used; things like namespaces (fallbacks), attributes etc etc ...
many things play a role and i'm pretty sure that the critical parts of
context are quite optimized; for sure many (simple) docs can be
processed using plain tex but as soon as you need a bit more ...
(btw, xml in mkiv is quite different, since it operates on trees)
