:> Usually echo is a shell-builtin, while `nice' is an executable,
:> and `nice -n20 echo' might also run a non-builtin version (/bin/echo),
:> which makes stats look differently.
:Mkay, that explains the difference:
:~:# while true; do /bin/echo "foo" > /dev/null; done
:27.5%Sys 51.3%Intr 21.3%User 0.0%Nice 0.0%Idl
:But it doesn't explain why is interrupt load so high. At least for me ...
:yet ... ;).
I get 18% ish. Ho! I'll track it down.
