If it isn't too far away, I'd join you :-)
I've dug in our archives, and lo! I have found the reference in question.

#This is implementation dependent.  On the current BSD system, printf
#is significantly faster, for strings that don't contain percent signs,
#than [f]puts calls.  I expect to make [f]puts just call printf in the
#near future.
