Questão why all the unprocessed_text left in script.

what the reason for leaving all that in a script. The farmer script has over 900 line of code it self and then you add that its over 1800 lines. Half that not being used but has to be read by the CPU. Adding load time and lag.

I have the Firestorm LSL Preprocessor option turned on for developing code. For browsers that have that turned off you will see extra items, but they are just comments which means that they are ignored, and so as far as I am aware do not add any processing load (at least nothing significant as far as I am aware) and the code is optimised so in itself will be more efficient.
