When my laptop said bye bye because of the heat I thougt it might be the scheduler, which was a mistake since I got 30 C reduction on full load after cleaning. Therefore, I don't think that there is any problem. I was just curious why both processes are hopping around, because I would naively think that should not happen. Note that I am neither software nor hardware expert, but a mere user of both. I tried the 4BSD scheduler just because Dough asked if I did. For me the question is resolved and I thank all of you for the replies. > Have you read Daniel Kalchev's reply in this thread? > He explained very well why that's not a problem usually. No, I haven't received that one. Regards, Momchil
