Slow compared to decent standards of what a word processor needs. For reference, WordPad perceptually opens instantly for me, and has felt like it opened instantly since Windows 95, I'm pretty sure. I am saying that both LibreOffice and Google Docs are examples of software that take way too long to do simple things because they're busy doing complicated things that I don't actually care for. (And arguably this isn't really their fault per se, they're both designed to compete with / follow the expectations set by Microsoft Office of what an office suite is, and those expectations are that all the complicated things are available).

> Local - as in not making connections on the network - in my opinion, will always have a speed advantage though.

Depends what you're doing with the network. I do just about all of my work in the terminal with a mosh connection to a cheap server a couple hundred miles away, and I never feel perceptual slowness from my machine not being local, unless I am literally in the subway or in an elevator. And I actually gain a lot of perceptual speed because I can close my laptop and switch to my phone instantly and see the exact screen where I was.

If you're streaming binaries from the network or trying to pump animations on a 2048-by-1536 true-color retina display, yes, remote is going to be slow. Half the tweetstorm's point is that you shouldn't be designing software to need that in the first place.
