Why does VPN drop my 1gb Internet to 5mbps on Android boxes but only maybe 20% in windows?

Why does surfshark drop my 1gb Internet to 50mbps on Android boxes but only maybe 20% in windows? My firesticks, Onn boxes both 4k and pro all drop to anywhere between 40mbps to 100mbps but windows just takes a much smaller hit? Is there any fix? Tried surfshark and expressvpn. I am guessing the boxes and sticks are just not powerful enough without bottlenecking somewhere but hoping someone smarter then me knows for sure. Windows I get 750mbps with VPN off and 610mbps with it on. Anyway to get the android based boxes/sticks up to speed?
