Ough, does this mean that for a multi-user scenario of 2 non-root users "A" and "B" each running exactly 1 process with nice level 0 and 19 rerspectively that both share ~50% of the CPU *and furthermore* that that user "B" does never ever have a chance to be nice to user "A" although his process should really use only those CPU cycles not eated by any other user ? If the answer is yes what's about extending the current behaviour to consider (optionally) nice level of running processes in the case where CONFIG_FAIR_GROUP_SCHED is set ? But anyway the initial email reports not a regression related to the ondemand governor. -- MfG/Sincerely Toralf Förster pgp finger print: 7B1A 07F4 EC82 0F90 D4C2 8936 872A E508 7DB6 9DA3
