fairly kernel strangeness

[synhedionn]

hi,
I thought the normal linux kernel fairly gave time laps to each processus; but so, how is it possible that it happens Firefox and its plugins to get 100% of processor(if 100 processus are loaded, it shouldn't overpass 1% of processor)?

The kernel is not fair! Jobs can be prioritised. I don't know how Firefox does it, but there is a command called nice which alters the priority of a job so that it can get more or less core time than it would otherwise be entitled to.

You can use nice to downgrade a non-urgent job of your own (make it nicer!) but only root can upgrade a job.
