</div>Your CPU is actually only ever running one program at a time (with the<br>
exception of hyper-threading). The way multitasking is done is the CPU<br>
is interupted at regular intervals and it decides which program to run<br>
during the next interval. Usually it does this switching frequently<br>
enough that it is seemless to you. It appears that all of your apps<br>
are running at the same time, when in reality they are each taking<br>
turns at the CPU. When you renice a program you tell the CPU to give<br>
that program lower priority and it won't get as much time on the CPU<br>
as programs with higher priority.<br>
<br>
If you are not CPU bound but are I/O bound then renice will happily<br>
let your program have all the time it needs on the CPU and thus you<br>
will still have I/O problem.</blockquote><div><br>Thanks a bunch, that's good info for me! So basically if the process isn't a CPU hog like f@h, but rather something that's using the HD, then renice isn't useful for /that/, right? That's good to know for future issues.<br>
<br>Thanks<br>Bob <br></div></div><br>
