Personal anecdote: my laptop (6 years old and outdated long before it was manufactured) was thrashing with 99% ram used and disk bandwidth maxed out due to a combination of a 100-tab Chrome monster and doing pacman -Syu on my Arch Linux WSL (I think it might be fixed now, but some time ago WSL file cache would eat all your Windows ram). After accidentally clicking on a pdf document Sumatra somehow still managed to open it in roughly 100-200ms.
I think it might be the only Windows program where I've legitimately been surprised by it's speed.
