It'd be cool if someone would replicate this on Linux under X11 and a few Wayland compositors, and throw urxvt, rxvt, xterm, aterm, and some others in the mix.
And Konsole. I love it. Too bad it is tied to KDE libs. It also feels quite snappy to me.
I'd like to see Terminology perform there.
When I first switched from the terminal emulator that came with the first DE I was using (gnome 2?) to urxvt, it seemed very fast. When I later switched to Terminology, it seemed even faster. I've stayed with Terminology. I agree it'd be very interesting to see a proper comparison between Terminology, urxvt and others.
