I haven't tried it on SuSE. Although I do have a OpenSuSE VM I use. It's just straight static (normal?) filesystems.
No LVM or BRTFS. But I like SuSE. We run SLES on a few servers here, those do have LVM and hardware RAID.
I don't know what kind of CPU you have, or how much RAM. But from my point of view...
4.7% and 2.1% aren't that bad. Less than 7% of your total CPU.
Your memory (RAM) might be slightly more of an issue.
20.4% and 10.4% are over 30% of your RAM. But still nothing to worry about really.
You will have to su - to root.
Then edit the /lib/systemd/system/plymouth-start.service file
With pluma, nano, or vi. (whatever you're comfortable with)
Change the second to the last line from...
save the file. Reboot.
