Renicer has been discontinued
Email me when discounted: 
Renicer allows you to adjust the amount of CPU time each application gets. The Unix underpinnings of Mac OS X allow users to assign priorities to processes with the Renice command. Higher priority processes get more CPU time and vice versa. The downside is that you have to use the terminal, and you have to know the renice syntax, process ID's, etc. Wouldn't it be nice to automatically adjust application priorities on the fly? Renicer is designed to run in the background, and automatically prioritizes whatever application is in front. It also ups the priority of the Finder, Dock, and Window Server. Renicer is designed to be more...

It appears to have changed to a background-only application. It no longer appears in my dock or application switcher. As to performance, I can't really say. I've preferred Renicer to the other similar apps I've tried. I genuinely believe there is a slight speed bump, but I have no official tests to prove it.

Quitting "renicer" killed all (!) running apps within a second. No chance to save any open project... >:-(

Nicely done and I bought it for a dollar along with Tiger Cache Cleaner when Northern was running a special. If you want to use Terminal, yes, you can do all of this, but Renicer actually allows you to change things easily and works well. It is in my Login Items at startup.

I hate when people charge money for stuff like this.A simple google search and about 30 seconds of reading and you will be able to do this on your own for free.

You're kidding, right? I just wrote a program that has more functionality than this crap using 4 lines of code. Four!!! It makes the front app hog the CPU like this program, and as an added bonus there's the option to bring the whole front-most program to the front (like in Mac OS 9).

I just love these "I can whip up four lines of code to do the same thing" kind of comments.

Mate, I can't, so I'm quite grateful for the efforts of others who do.

And can your four lines of code renice on the fly? I wonder.

Not everyone is a gun software author. Not everyone is a terminal command-line genius. Not everyone has the time or inclination, or even the desire, to be so.

So for developers who take the time to write software, test it, release it, upgrade it, iron out the bugs, respond to their customers -- all of which this person has done -- and then charge a very modest fee ($8.95 is peanuts in this day and age, and for an extra $1.05 you can have Renicer and Tiger Cache Cleaner).

Yes, there are free utilities that do similar things, but that's the prerogative of their authors. If you don't want to pay, great. And if you want to write your four lines of code and use that instead, please feel free. But don't bother to burden us with your griping. It's not clever, it's not original, and it's certainly not educational or interesting. In short, it's a waste of your time and mine.

Applescript to the rescue!
Punch this in to Script Editor run it. You can even save it as an app, but you'll have to force quit it.

repeat

tell application "System Events"
set currentApp to item 1 of (get name of processes whose frontmost is true)
end tell

do shell script "sudo renice 0 -u YOURNAMEHERE" password "YOURPASSWORD" with administrator privileges
set currentPID to do shell script "ps -axww | grep '[/]" & currentApp & "'| awk '{print $1}'"
do shell script "sudo renice -20 -p " & currentPID password "YOURPASSWORD" with administrator privileges

tell application "System Events"
repeat until {currentApp is not item 1 of (get name of processes whose frontmost is true)}
end repeat
end tell

end repeat (11/20/2003, Version: 1.0)

I think this is great: true, it adds a small extra lag when switching between apps, but once in the app, speeds are up without having to renice from the terminal - this is particularly noticeable for me in using Virtual PC and Retrospect backup - the backup being quicker is a real plus.

The only thing that puzzles me is why it takes so long for Renicer to quit - maybe it's because I don't have Persist set to On, so it resets everything's Nice value to 0 when you quit it?
