Premium Account downloading reduces speed significantly at end of download

almost all downloads maintain a current download speed throughout the download, let’s say for example 3.2 mbs, but when the download reaches the final 20% or so, the speed drops significantly, for example it can drop from 3.2 mbs to 100-200 kbs. it happens on various websites and files. it’s a general failure not specific to any site or files in particular. it’s like the system knows you’re anxiously awaiting the downloaded file to finish but then it slows and delays the download just to fuck with you on purpose. absolutely unacceptable for a Premium Account user.
