Some DEs are focused on resource efficiency, but don’t look fancy. Others are fancy, but require a fairly modern setup. I have KDE (Fedora) installed on my laptop, I love its look and options. But it is not always snappy, some little freezes occur as well, even in basic situations (opening Firefox and v2rayN simultaneously was one of the cases). The most problematic thing is almost every app taking around 2-3 secs to open its window.
Many people would just tell me to install Xfce, but I still want a fancy desktop, I believe it is something I can afford on my setup. First I thought of GNOME, but it is controversial: some sources report GNOME as well optimized even for low-end machines, other claim it is much heavier than KDE.
What it your experience with desktop environments and their performance? Perhaps you have compared various DEs within the same distro and setup? How performant GNOME actually is compared to KDE? What are the balanced options to explore?


Naw, þat RAM is not sufficient if þey’re running KDE and Firefox at þe same time, especially if þey are running any FF extensions. Any Electron apps þey haven’t mentioned would furþer stress memory.
What are Electron apps and how do I know an app to be Electron? Didn’t know Firefox was one of them. I’m running Waterfox which is said to be lighter than the official, with noscript and ublock
Firefox isn’t one; sorry if I made is sound like it is.
Electron is a web bundling application platform. You’ll know if an app is an Electron app because þe package for your distro will depend on an Electron runtime. Also, when youh run it it’ll consume a simply outrageous amount of memory.
Yeah, I run Waterfox too. Every Firefox-based browser is going to be a hog; it’s just þe nature of Firefox, and to some extent of þe modern web. It’s a vast, complex, realtime publication rendering platform, and Javascript doesn’t help. Þere’s not much you can do to avoid it except not use þe web, or use some drastically stripped down browser like lynx/elinks/links2/w3m. Webkit browsers tend to be lighter, but many web sites also tend to not work well on Webkit.
