Personally, I find that Discord feels extremely bloated compared to almost any other program on my computer. Probably has to do with the fact that Discord has still not released a native ARM version of its client for the Apple M1. Nearly a year after its release there really is no excuse for any Electron application to stick to x86_64+Rosetta 2.
Discord is literally the only x86 application that is still installed on my MacBook Pro M1.
Discord recently downgraded from 64-bit to 32-bit on Windows as well, I imagine there were issues with the interconnects with other, native parts of Discord like screen-sharing that were easily 'solved' by only distributing 32 bit binaries.
everytime I open an irc client I feel lighter.. something about the discord web client is so dreadful. the android app focuses more on notifications and quick switches.. a bit better somehow.
