With that I can press the number "1" and it will display the CPU usage for each CPU/core. You can also press the letter "i" and it will hide all idle processes to clean up the display a bit.

Therefore I use top -s 5 -u which cuts the overall CPU usage of top by 80% too. Sampling every second is not useful for me. Therefore I use

Save a few keystrokes and use "-u" which is "an alias equivalent to: -o cpu -O time". Close enough. top -R -u works OK and cuts the CPU usage of top by about 80%. The segmentation fault seems to occur with the -F, not the -R.

It only displays as many processes as will fit in the shell window. Is there a way to make it scrollable? What I don’t like about Top is that is that you can never see every item on the list.
