The UI seems interesting, and I'm a sucker for RIIR, but why do terminal emulators keep trying to use "blazingly fast" as a feature? They're all fast (except the hideous electron ones), they're white text on black rectangles.

I don't get it either - I use Windows (the default cmd, Powershell and Cmder), Linux and MacOS and don't recall a terminal emulator being slow... ever.

Yet when the subject of terminal emulators comes up, there are often comments from other HN users insisting that Windows terminal emulators are molasses compared to MacOS, or that this emulator is much faster than that. I don't get it.

You might be a particular type of person... I don't remember Windows Cmd being not slow, ever. It feels extremely sluggish. It supposedly has something to do with Windows ConHost, but I don't know about the details.

In fact, even most terminals on Linux are unbearable to me. Not only do the antialised vector fonts tire the eyes on sub-4K screens - most of the terminals I've tried feel slow as well, though not as slow as Windows Cmd.

Personally I use xterm with bitmap fonts whenever I can, it feels sooo good. It has both crisp font rendering as well as being reasonably fast/responsive. (It's probably not the fastest ever in throughput if you want to display /dev/urandom, but that's not my benchmark).
