Sometimes it is easy to be faster than everyone else by simply having less code. Sometimes you need to think about how you can do as little as possible instead.

XTerm has the logic for handling partial screen updates and window obscuring other terminals don't bother with because it was written in an era that these weren't mere 10-50msec delays but 100+msec delays; Anyone who used dtterm on a sun IPX knows what I'm talking about

I'm also a Terminal.app user.

I'm amused to find that XTerm still include a Tektronix 4014 emulator.

OTOH Alacritty can supposedly redraw the entire terminal in 2 ms, so perhaps those tradeoffs have changed over the last few decades.

An interesting side effect of Alacritty's choices:

> alacritty and terminal.app are fast enough that they’re actually limited by the speed of tmux.

FWIW, We're working on adding native support for scrolling. Someone has actually made an attempt at it recently: https://github.com/jwilm/alacritty/pull/657

Initial testing has shown it not to (noticeably) impact perf in our highly unscientific benchmarks.

Ah great!

I'm a native Windows user these days, so I can't use it quite yet, and as such, have fallen behind the time on news.

That's awesome! No scrolling is what prevents me from using alacritty. Hope this gets merged!
