If you really want your code to be as efficient and minimalist as
possible, you are better of with the plain format than with ConTeXt
in any case. Personally I prefer to optimize on complexity and
readability of my sources instead of on machine clock cycles.

That said, metapost graphics are, in general, heavier than \framed.
If you really need thousands and thousands of those boxes, a macro

         {\vrule height \ht\thebox
                 depth \dp\thebox
                 width \wd\thebox}}%
      \box\thebox }

can help. But if it is only a few, simply use \framed.
