[...] of course: you asked for the two chew's to be treated like that and CFS delivered it! :-) nice -10 means the two chew's will get ~90+% of the CPU time, and all other nice 0 tasks will get <10% of CPU time. in the previous mail i have described the new exponential-scale nice levels that CFS introduces. In practice this means that vanilla kernel's nice -20 level is roughly equivalent to CFS's nice -6. CFS's nice -10 would be roughly equivalent to vanilla nice -80 (if it existed).
