If any of you are interested in the script, just text me her and I will upload it. So you would also need to limite RAM usage, and I/O usage if that would conflict with othe apps. have a peek here
However, your method, ie, nice, does nothing to keep the total CPU load below 100% (per core), in fact this has already been said in the article, nice is not a More Mac Sites: Macworld MacUser iPhone Central Submit Hint • Search • The Forums • Links • Stats • Polls • Headlines • RSS 14,000 hints and counting! Many non-interactive programs are not programmed to handle SIGSTART--it is assumed that these signals are used by interactive programs and not relevant for background processes. I use Activity Monitor to watch both processes and CPU utilization and can see the CPU spike as soon as the cputhrottle process ends.
Keep going! 25 July 2010 Are you a mathematician, physicist, scientist, or just a curious person? Note: To get the PID, run first the top -u command in one Terminal window. You might as well just downgrade your system if you plan on doing that.

It has been reported by several users that cpulimit works fine even on SMP hardware, but consider that if you have more than one cpu there is a little difference in Then, the next task is to change the priority of the process (let's say it's Safari we want to make behave nicely).

Find the process identification number (pid) of the running process and run the renice command: renice -n -5 pid Just as you lower the scheduling priority, you can also raise the But if you limit RAM, then the restricted app would start paging and swapping, which would increase I/O.

Some folks have noted that gunzip says that the file is not in gzip format. Optional step - Keep the software running As you can see in the comments, some users face this problem that the cputhrottle terminated out of sudden after few hours of running cputhrottle makes use of the task_info, task_suspend, and task_resume calls. http://qaisoftware.com/cpu-usage/whm-cpu-usage-limit.html Much good Karma to you for this!
Thus, at the end of the day if you want to reset the priority of the process back to 0 (nominal), the use "sudo" to run the renice command. Mac Cpu Throttle App Reply Sean says: August 16, 2013 at 1:47 pm My old MacbookPro6,1 thanks you for extending his life a little longer. You need to download it from http://cpulimit.sourceforge.net/ and make sure you have the latest version of the developer tools. [ Reply to This | # ] Nice does nothing to reduce
I've seen a "Processors" preference pane, allowing for deselecting processors on-the-fly Also, no luck. Stay tuned! 10 August 2008 Big thanks to Alexander, who made a huge donation to cpulimit. 16 February 2008 As promised, the subprocesses control implementation is at last in cpulimit svn. Definitely ugly, but I can't think of a better way to accomplish your task except perhaps running the process in a VM or binding it to a single core.

Can I limit it to 10%? The work of cpulimit is done all in userspace, so it doesn't interfere with the Linux scheduler. Why a browser must eat 50% or more of my CPU? This was my first attempt at a solution, to no avail.
Yours; Reply maui says: November 1, 2014 at 9:38 am sure why not. Video rendering uses a lot of RAM and often does a lot of DIsk I/O. Even if the CPU is IDLE this hack will prevent the application to use the CPU during Sleep Time (in contrast to renice/nice commands which will take all IDLE time).
