Theory vs. practice...
Authored by: maxgraphic on Jun 19, '03 04:00:28AM

man nice says nothing about not using -20. In fact, man renice recommends "anything negative" to "make things go very fast."

And, yes, I would call DropStuff or anything I've ever used from Aladdin a "bad design." I don't want to get off on a rant here, but StuffIt has a long history of major suckage and I've spent a fair amount of time wondering how it won out over Compact Pro, a far superior compression app that complied perfectly with Mac OS human interface guidelines. StuffIt still, years later, prompts for a filename at the point your create a new archive. Expander still dies silently when it encounters an error. The whole package needs a rewrite desperately.

Anyway, getting back to the point, I am not surprised at all that DropStuff benefits from renicing and thus this is a perfectly valid and usable hint, despite your objections.

interesting ideas about dropstuff, I was more thinking of for example other apps like Word eating CPU time even if you only read a document... or if it's in background... (where the priority discussion comes in)

cheers

There's no such thing as "background" and "foreground" any more. All applications run at the whim of the system scheduler without regard for which one you (the user) happen to be interacting with at any given instant.

(There are some exceptions. Virtual PC 5 tries to set its CPU usage differently depending on whether or not it's the active application. I don't think that feature actually works.)

Word eats up CPU time because you have background spell-checking and pagination turned on. Turn them off, and your problem will largely go away. Not completely, because Word as a Carbon (and poorly Carbonized, at that) application still uses the old event polling scheme, which means it constantly has to run a little loop rather than waiting for dispatches from the OS. But that's not that big a deal.

An even better suggestion is to use TextEdit instead of Word. It's faster, smaller, and comes with your computer for free.

hehe, I don't use Word. I was just using it as an example of bad software. With background, I exactly meant what you explained ;-)
cheers
