The keyword here is fancy. Hexchat is an IRC client, sure, but it is minimalist. That would be like comparing a text file to a PDF and asking why the PDF needs so much more RAM when they're basically the same.
I feel like you're mutating the argument from "electron uses 10x RAM compared to native apps" into "an IRC client doesn't need to use so much RAM"
The proper comparison would be either a full, feature complete native Slack client with all the same bells and whistles that runs under 100mb, OR an electron port of hexchat with its text only interface that uses 1GB+
Well, I would understand a chat client taking more RAM should I ask it to pare & display some HTML, or videos, or PDFs. I'm not. I'm using Slack just like IRC - 3 users and a single channel even. No images, no videos, no HTML, no link previews, etc. That thing still absolutely melts down my CPU and RAM.
I get what you're saying, but we already know that electron (specifically embedding a whole browser with DOM) is the culprit. There are some native UI toolkits with bindings available for NodeJS, if slack was refactored to replace electron with one, it would probably peak at 2x as much RAM than HexChat rather than averaging 10x to 100x.
100x now? You're saying there are electron apps in the wild using 10GB of memory? I was trying to argue that the 10x claim was an exaggeration but you've just leapfrogged that.
