Does merging packages make Sims run better?

Years ago in a Discord chat, an experienced modders explained that merging cc can be an effective way to shorten loading screens if a person had a graphics reader? that was the kind that scrambled data as it loads. Apparently, there are other ones that do not. I'm not a PC person so I have forgotten the correct terms. The upshot was, that if you had the reader that randomized data it would help, if you have the other it would not.
Mine is a scramble one, I noticed a definite improvement when I merged my cc. My thought is, that the people who say it doesn't help have better PC's than I do and have the readers that don't scramble data to read it, therefore it doesn't help them.
My advice is to try and see if there is an improvement.
