ACK

The typical bottlenecks in a script are usually IO operations, database
stuff or bad algorithms (bubblesort vs. quicksort for example). Printing
out data shouldn't be an issue at all in most cases.

Yep. Additionally I often prefer printf/sprintf when there are a lot of
variables or expressions to embed. It's even slower than a plain print
or echo statement, but much more flexible and readable.
