If you want me to help you, please help me get good info. It's very important to me _know_ wether this is a boot slowdown or a generic - assertions are not good enough, I need hard facts. My own laptop (A Toshiba Libretto 110CT) does a make world in about 8 hours (and it always has). Interrupt harvesting has not made a noticable difference (I have not been keeping records, but an overnight build has not yet progressed into my breakfast).
