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? -- regards Simeon > > nate > > > -- > ::: > ICQ: 75132336 > http://www.aphroland.org/ > http://www.linuxpowered.net/ > [EMAIL PROTECTED]
