i7 3770, 32GB RAM, dual SSD and two HDD setup, Windows 10 x64, everything flies, absolutely everything updates before I finish half-blinking my eyes. I have 2-3 Twitch streams running 24/7 and still have 30-50ms in any game I enter.

Yet, Slack manages to have lag between pressing Enter and showing a message. It's baffling to me how almost nobody doesn't seem to have a problem with that. Miranda IM worked much faster when connected to 6 networks... on a machine that was 10x slower than my phone.

Like, come on.
