ocreval VS htop

In my research I extensively use a software suite that was developed in the early '90 in the Information Science Research Institute in Las Vegas called ISRI tools for OCR evaluation. This tools were ported for modern systems and are maintained at: https://github.com/eddieantonio/ocreval. The tools are used via Linux Terminal and they give large amounts of data on different aspects of text recognition process, and the output is in plain text format.

Probably everyone knows about the "top" command. Htop is similar, but gives us a more user-friendly output. It shows processes using the most resources, how much available resources you have and who runs those processes. For more information, visit https://htop.dev/

determine which processes consume specific resources (in your particular case even a "5 minutes session of staring at htop" would do the trick.) (Alternatives: ps -ef, ps aux, top, glances ... )

When you see the laptop throttling, is htop or another monitoring program showing that the RAM is full, or is it only partly used?

I like htop to check system resources

try htop. It's already on Ubuntu, not sure about other flavors.

Program it in yourself: https://github.com/htop-dev/htop

htop is a colour-coded command-line system monitor, process viewer, and process manager. It shows a list of processes running on your computer ordered by CPU usage
