But sometimes you are faced with squeezing all the performance you can out of a specific processor.

And then you apply it in testing, note the regression, and either don't apply it in production or apply it as you push out an update.

If the software will be running on the machines of "customers" and you do not "control all the processors" they use, then you're not in the "sometimes" I was discussing above.
