From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Sudo cpupower -c all frequency-set --max 0.8GHz No more spikes 😎👍👌
That'd just prolong a mild spike instead
Sar?
Yeah, so this is the best one I've seen so far.
I've just installed it, but I'm stumped on the documentation on how to find the name of a high-load process from 10 mins ago.
Install and start the monitoring
sudo pacman -S sysstat
sudo systemctl {enable,start} sysstat
Find what processes were running 10 minutes ago
(first wait 10 minutes)
sar -P ALL -f /var/log/sa/sa$(date +%d -d '10 minutes ago')
nothing happens.
fyi, systemctl disable/enable has a --now flag
