not really. IO is not CPU bound and nicing a process only changes its CPU usage priority (on linux 2.6)
Now, if you have a processes eating up 100% of the CPU, renicing a processes that uses heavy IO *can* have an effect as the program using all the IO could gain(or loose) the ability to get to the CPU in a timely manner. generally speaking though, renicing and IO bound task wont make any difference Carl Wilhelm Soderstrom wrote: > On 03/27 10:29 , Tony Schreiner wrote: > >> Does nice and renice have much of an effect on I/O bound tasks? >> > > I don't know the scheduler well enough to know for certain myself.
