This is about the classic conhost, not the new Windows Terminal.

Typing inside of the default WSL terminal feels amazing (2018)

#22The surprising thing here is that this is the Ubuntu terminal. Indeed, each keystroke goes through the input driver, to USER32, through the console code, to the terminal process in question. But then it goes through a virtual input device, across the VM boundary (which, on Windows is a VM exit plus an entry), through the Linux input driver, into dash (or whatever Ubuntu uses these days), and then all the way back out…
Note that this content is one year old. At that point, WSL was not a virtual machine, it was Linux syscall emulation in the NT kernel.
Does that mean it's faster or slower now?

WSL2 is generaly faster:

#26Long time ago we used RXVT because XTerm and ATerm were both too slow

I think most of the latency between key press and rendering to screen is in the layout / drawing phase.
Forwarding a few function calls is usually pretty fast, the text layout and rendering part is what is slow. Especially since many UI frameworks don't render individual characters; you may end up redrawing a full line or more for every keystroke. (I only have experience with macOS / Cocoa rendering, and I was surprised how slow it is compared to all other things my code does)

#28How I wish that I could use the new terminal app on the windows 10 build that is installed on my work Laptop.
Wow your work laptop is up to 10 already? We've started to plan our migration.

RXVT sucks, but typing on it feels so good that it is what I use.
