I am running un tar i.e tar xzvf abc.tar.gz on Beaglebone green. This seems to be using too much CPU. When a untar operation is in progress, i see via top command the CPU usage.. not sure why it seems to be creating 2 different processes, any idea why???
PID PPID USER STAT VSZ %VSZ %CPU COMMAND 626 625 root R 1956 1% 64% tar xzvf abc.tar.gz 625 612 root S 1960 1% 12% tar xzvf abc.tar.gz
How can I limit the untar process to not use too much CPU? There is a time critical real time process which isn't getting CPU and it gets effected whenever untar is run. Hence the need to limit untar in some way to not use more than may be 40 - 50 % of CPU at any time.
