response by the creator of alacritty. Looks like alacritty might become low latency as well as high throughput?

OTOH, one of the maintainers of emacs appears to be offended that anyone would dare to measure its throughput?pic.twitter.com/veHzmrMYzO
-
That's too bad -- if emacs was only 10x slower (throughput) than terms, I could use emacs for everything, but at 100x it locks up too often
-
Whoops! Typo! Even 100x slower might be ok, but emacs has 1000x worse throughput than most terms

I didn't see in the article, how did you actually measure the latency? Is it reproducible w/out hardware? Did you just high speed video it?
-
Time measured is internal keypress sent to GPU memory, reproducible without hardware, but missing 40ms+ of latency for a typical setup.

Thanks for looking into this. Are these terminals (other than http://terminal.app ) running as X clients under XQuartz?
-
AFAIK, only st was using XQuartz. To see if XQuartz is inherently slow, I tried another terminal under XQuartz and it wasn't slow.

this post is *extremely* rad and quantifies something I've been looking for writing on for a long timeeeee
-
I'm curious if there's something to measuring STDOUT *latency* (vs throughput) as separate from keyboard latency - I feel like seeing how
