You’ve set up your Homebridge server, have a Pi acting as a CUPS printer server or covertly installed the Pi with an old stereo now serving as Airplay relay device. Things are getting a bit laggy or unresponsive, first step after rebooting the device is to SSH in, and install HTOP.

HTOP is an alternative to top, a ‘table of process’ task manager, HTOP benefits from a semi graphical interface showing processor, memory and swap usage in the upper section of the screen, and rolling running process review in the bottom two thirds.

Will start the process, of downloading the package and installing it.

Once its installed, its just a case of running ‘sudo htop’ to get the process working and ctrl+c will stop it.
