Hi Sonny
I am not sure what you are asking here. 65-70% idle time (or 60-65%) is fine.
2.6 is also not very meaningfull, there are a lot of changes between 2.6.0 and
2.6.23 :)
Why should you upgrade kernel ?
What bandwidth do you handle ?
What kind of platform is it ? (a new kernel wont help much if its a real old
machine, or old NICs)
You seem to have some bandwidth problem but focus on cpu affairs...
