Hi Marco,

re:

But no, this isn't correct - if you are doing that just a couple of times a day it is not necessary for the code to execute as fast as it possibly can, it only needs to execute in a reasonable time for accomplishing the task at hand.

For example if it currently takes 1 second to execute the script, optimizing it down so it's instantaneous will only save you a tiny amount of time if it's only performed infrequently.

So the actual practical usage is an important factor, it's not worthwhile to put a lot of effort into optimizing things that are not causing an actual problem in real life use.
