No, I can image if you google for "nice" that should yield 2e15 unusable results.
This is the man page:
http://www.manpagez.com/man/1/nice/
And you use it like:
Code:
nice 40 myperlprogram
It will schedule your progam below most others, the higher the nice value, the nicer your program behaves.
But ...uhm.... it doesn't make your processor run slower when your program is the only one to run. Running any program requesting full power
will increase the clock speed.
It will be difficult to achieve that as all power saving schemes are based on gives you as much CPU power as possible when you
need it.
You might want to check settings of
powernowd, and see if you can make it stick at a low CPU MHz value. Certainly you will google useful results, and also check "CPU clock throttling". A lot of sites will direct you to the speedstep.c program but I am not sure you are willing to recomplie your kernel for this, and it will be difficult you make your CPU listen to full power again. There might be an entry in /proc/sys/cpu which allows you to limit the clock speed as well.
