As it happens, Context will accept the same simple file as pdftex 
without complaint. Unlike pdflatex it won't choke if its own macro 
call etc. are not employed. So here is a file:
------------------------------------
Hello, world.
\bye
-----------------------------------
pdftex hello.tex
 yields 5498 bytes.
texexec hello.tex 
yields 21178 bytes, and takes 21 seconds to run.  It appears that this 
is just 15,680 of fixed overhead.  If I add some text the overhead 
grows to 16,197, not a big increase.

but it is consistently bigger.
