Reduce scheduling interval on Linux...

[Peter <peter@atterfjall.pp.se>]

On Red Hat linux a delay 0.0; would mean that process (thread) will be 
out of processing for 10 (ms) by default. This is a kernel 
configuration, and a good value in many cases. For my application I 
would like to reduce this time to maybe 1 (ms), or try to optimise it to 
the perfect value for the application. Yes, I know I am trying to make a 
RTOS of something that is not, but this is really the only thing 
missing, and the advantages of having a full system at least for 
development makes me rather accept 10 (ms) that to have to cross compile 
all the time.

Has anyone been changing this and could point me in the right direction. 
Tried to do this once on Red Hat 7.0....but only got confused by the 
parameter names and the comments around them in the kernel.... Are you 
aware of any other full systems, beeing it Linux, BSD or whatever were 
this value is lower or easily could be changed ?

( Yes I am aware I will take away lots of machine power with this short 
scheduling times, but power is not yet an issue)

Thank you for any help on this
