For anything taking less than about a second a progress bar is, as you have amply demonstrated, a complete waste of time. As a general thing aim for a progress bar update about every 1/10th of a second. That means having some idea of how long each iteration of your process takes an perform a progress bar update every 1 / (10 * iteration seconds) iterations.

Premature optimization is the root of all job security
