:> 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 ... ;).
:-- 
:Hasso

    I get 18% ish.  Ho!  I'll track it down.
