I can pick a reason out of many, and that would be the software. The fact is that, even as they are computers and machines, the softwares themselves have particular design cap. A software that was designed for systems with a narrow word size will most likely have issues as more and more words are used on it. I don't know if you understand what I'm saying, everything has a cap, once that particular meter is approaching, systems tend to slow onwards.
When it comes to the hardware part using the same technology, it might take a longer time to do basic arithmetic on larger inputs.
When you're under using a system, it tends to have a lot of space, excess, to perform its functions, but as soon as it is nearing its limit, it will slow down so as to accommodate all the processes at once.
