I am running a Spigot server with MineOS… How can I verify is the Minecraft server is using more than one core?
htop would be the easiest way, use the following command -u flag is for user so if you use turnkey and made the user as mc put that. Otherwise user will be what ever you called you non privileged profile.
example
htop -u mc
htop -u username123
You can also do
pidof java
htop -p pid
pid being the number that pidof returns so…
htop -p 1234
htop -p 4125
etc
Thank you @Ank!!
Sorry for the delay… making a ton of changes to my home network, but I am setting MineOS back up.
