Is there any way to change the priority ('nice' it, in Unix terms) of
a running application?

I'm doing a lot of manual archiv/zipping at the moment, and it'd be
great if I could set the bloody things to low priority so they don't
take over my computer - it's only a mini so it's a bit disk bound.

Cheers - Jaimie

Not used it, but is this any use?

There are some freebie ones as well, but they all seem to want to
renice an existing process, not maintain priority lists for eg. making
sure zip runs with low priority.



Cheers,

That seems pretty effective, ta. Not sure why my own hunts didn't
track this one down! Poor choice of search terms, I guess.

Isn't it funny how much mature wisdom resembles being too tired to bother?

Similarly, I'd like to be able to restrict an application to using an
arbitrary percentage of CPU power. Even if nothing else is happening, I
want some apps to each use a max of only (say) 50% of one core.

I suspect that this isn't actually possible, though.

Not under OS X. nice doesn't do that. Some variants of fair share
scheduling algorithms allow for it.
