nazdar,
mne sa nejak nepozdava ten tvoj zapis 'nice make -j20'. Aky level si zadal
pri nice? Volba -j20 neznamena nahodou, ze mas 20 (-1) procesorov, resp.
kompilacia ma byt optimalizovana na taky pocet procesorov?
Ja mam v make.conf nastavene premenne takto:
MAKEOPTS=3D"-j2"
PORTAGE_NICENESS=3D"15"
mam notebook s P-M 1,6 GHZ a nikdy pri kompilacii nemam problem s odozvou
systemu, ani ked nastavim taktovaciu frekvenciu na 800MHz (aby sa moc
neprehrieval).
s pozdravom
