But there are serious issue if you use FreeBSD as a desktop OS with SMP and SCHED_ULE, or? Because currently, my machine is barely usable if a compile job with parallelism is running. Movies stutter, Firefox hangs. And even nice -n 20 doesn't do the job in every case, as +20 seems not to be the idle priority anymore?!? And using "idprio 1 $cmd" as a workaround is, well, a kludge. I am not sure if TTY grouping is the right solution, if you look at potentially CPU-intensive GUI applications that all run on the same TTY (or no TTY at all? Same problem). Maybe, we could simply enhance the algorithm that decides if a task is interactive? That would also improve the described situation.
