linux-3.8.4: Compile times

In Phoronix Forum I have received feedback regarding the CPU time issue, as described below, see "CPU Usage Time Is Dependant on Load". Right now I use

3.2.0-38-generic #61-Ubuntu SMP Tue Feb 19 12:18:21 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux

So maybe this behaviour is kernel dependant. Therefore I compiled the latest stable Linux kernel, see The Linux Kernel Archives.

make menuconfig
time make
    . . .
real    69m59.311s
user    63m38.191s
sys     9m23.687s

It takes more than a complete hour on an AMD FX(tm)-8120 Eight-Core Processor, although basically only one core is used!
