Responding to my own post...
I realized that rand() may be exaggerating again, so I ran Rob's test
again with rand() added to the output and got these for comparison.
Concatenation took 1.42593598366. Multiple echoes took 1.53872704506
Concatenation took 1.75097298622. Multiple echoes took 1.98070502281
Concatenation took 1.66252112389. Multiple echoes took 1.82230710983

I guess the answer is going to be "It depends" on what you are doing.
