Running a Gentoo Linux at a 4-core CPU (i5) I realize, that compiling
packages using -j4 usually needs twice as long, if I run 4 BOINC
processes in the back ground (nice -n 19) too. Even considering effects
of invalidation of cache data this seems a too big impact in my eyes.
It looks for me like that the BOINC processes scales down the frequency,
when they are running. This behaviour however would be wrong IMO. The
frequency should be scaled just by the non-niced foreground processes,
right ?
