What is the difference between "user" and "sys" CPU usage?
I noticed that on the dashboard that one of my droplets spiked to >800% of “sys” CPU usage. It occasionally does this for very brief periods of time, and happens to occur at the same time as some high disk IO and network IO. It’s not causing me any troubles as far as I can tell but I was just wondering what “sys” CPU usage actually means. I was initially under the impression that it’s kernel processing load vs userspace load, but since it’s going well over 100% I’m not sure what it actually means.
It’s a single-core 1GB droplet.
