Be helpful
Posts to pop_os must be helpful. When responding to a user asking for help, do not provide tongue-in-cheek responses like "RTM" or links to LMGTFY. Linking to direct sources that answer the asker's question is fine, but it's advised to provide some explanation as to how you got to that source.
Critique should be constructive
We within the Pop!_OS community welcome helpful criticism or ideas on ways to improve. However, basic "It's bad" or other simple negative comments don't help anyone fix anything. When voicing a complaint about something, try to point out ways the complaint could be improved or worked around, so that we can make a better product for it.
This rule applies to both Pop!_OS and its projects as well as other products available from third-parties.
Don't post malicious "advice"
It can be funny to joke about malicious commands, however this is not the venue for it. Do not advise users to run commands which will lock up their systems, steal their data, or erase their drive. Examples of this include (but are not limited to) fork bombs, rm, etc.
Posts violating this rule will be removed, even if the post is clearly in jest. Repeated offences may lead to a ban. You may understand that the command isn't serious, but a new user might not.
No personal attacks
Posts making a personal attack on any user will not be tolerated.
No hate speech
Hate speech of any kind will not be tolerated. Any violations will be removed, and are grounds for a ban.

I haven't seen any benchmark where GNOME was more performant than COSMIC. Despite alpha status, it is already much more responsive than GNOME.
GNOME uses a single thread to render all displays in a multi-display configuration. This is often so slow that they need to rely on double or even triple buffering when the frame rate lags behind the display's refresh rate. Meanwhile in COSMIC, thanks to the thread safety features of Rust, it was easy to implement thread-per-display multi-threaded rendering. This means that each display is rendered and composited independently on their own respective threads.
GNOME's compositor also has an entire JavaScript runtime bundled inside of it, which it uses for drawing interfaces and handling application logic for those interfaces. All within the same process as the compositor, slowing down its event loop. COSMIC instead keeps the compositor process very lean, with all desktop interfaces running in their own isolated processes outside of the compositor via wayland's layer-shell protocol.
