I've been using
x265 to encode some video on my workstation lately, but I have a problem: even though I launch it using
nice -n 20 x265 to deprioritize it, it still slows the computer to a crawl while it's running. Everything still works, it's just... slow! I even see delays before the characters appear while typing in a terminal.
Do I have to live with this, or are there some other things I can try?
EDIT: Perhaps the following serves as proof that the nice value really is getting applied to
x265? Look at the
% ps -awux -O nice | egrep "x265|PID" USER PID %CPU %MEM VSZ RSS TT STAT STARTED TIME COMMAND PID NI TT STAT TIME COMMAND nobody 56654 789.3 3.7 785656 623384 11 SN+J 11:56PM 6:05.80 x265 --input-csp 56654 20 11 SN+J 6:05.80 x265 --input-csp i420 --bframes 5 -
