well on my celeron 450 all IDE system the user hovers around 10% and system is
around 10%. so Its not taking all the CPU. I seems that taking in input fromt
he CD drive limits other inputs to the system, in this case the ppp connection.
I mean I can push the cpu utilization up by just encoding a wav to mp3
and the ppp connection is fine. So would it be something in the way I/O
is being handled?
