@sun What proprietary drugs are you on?

I've been unfortunate enough to use windows and it's a lagfest where you spend most of the time waiting for windows to carry out your operations, or for the dedicated loading icon to carry on for ages.

Meanwhile on a free GNU/Linux-libre distro, with a Xorg DE, each UI operation and GNU bash command is executed instantly (sure there's a bit of lag on bootup while everything loads from storage, but the lag ends when that's over).

Some garbage Wayland DE's are a lagfest and some garbage software puts slow running operations on the display thread, but that has nothing to do with Linux.
