My CPU Usage is 100% while burning 4X on a RW as reported by MBM5, Speedfan, and win ME system monitor
I still could log into the forum, close and open a variety of applications.
I am running an XP2200+ on a KT400 system.
My 512Mb DDram 2700 are still 76% available
Did not believe my eye, searched the web and downloaded Wintop a MS KernelToy which seem to give more consistent CPU usage per process.
So the largest chunk is eaten up by Nero
- 60% during speed test
- 20% during the burn process itself.
This concurs with the high usage shown by cdspeed while measuring the transfer rate as said by Code65536.
During the verification phase, Nero will use from 5 to 30 %, maybe depending on errors encountered.
At the end, the obvious conclusion is that burning in itself only takes 20% CPU usage on an XP2200+. Don't know the maths for a 1Gh processor but it seem more than feasible.
A big slowdown can be expected during speed tests though.
