I guess I can start with mine; Having moved from openSUSE to Manjaro on my main system this week, I can do a partial comparison, especially as I’m using the same software and even ported my home directory with application settings. Of course this isn’t a proper benchmark, I’m citing what I remember from memory. Here’s a rough description of what I’m seeing so far:
- General system performance is roughly the same, possibly a bit faster by a barely noticeable amount. It’s hard to sense the difference between boot and login speeds as well as how quickly applications open, but I can say for sure it’s definitely not any slower.
- Memory usage seems to be a tad better on Manjaro. I’d estimate 300 MB to potentially 1 GB lower on average after many hours of uptime (5.0 GB versus +5.6 GB).
- CPU usage when idle seems to be a fraction better on Manjaro. The plasma widget shows roughly 0.3% to 0.6% CPU while nothing important is working… this may be a decimal or two lower than what I remember observing on openSUSE.
- Same amount of background processes kept open by the system: Roughly 400 processes (user with root) listed by KSysGuard, with about 440 in the first minute(s) after login.
