Although many people have written small programs for test
purposes, most of them run those programs in environments
tuned for running much larger programs.  In fact, if you
run a trivial program on a capable operating system it will
incur all sorts of overhead setting up for the possibility
of multiple DLLs, etc. that are never needed for "Hello World".

So a bare machine will indeed provide the most efficient
environment for "Hello World", so long as your calculations
value your own time as worth zero.

For a truly efficient solution, use a pencil to write
"Hello World" on a piece of paper and be done with it.
