<br>Greetings, <br> <a href="mailto:kernelnewbies@kernelnewbies.org" target="_blank"></a>
<p style="margin-bottom:0in">I want to optimize the performance of
the scheduler in the Kernel 3.0 in order to increase the number of
calls a Sip proxy server can handle.
</p>
<p style="margin-bottom:0in">I read about the scheduler in the
Kernel 2.6 and was able to find the variables MIN_TIMESLICE,
MAX_TIMESLICE, PRIO_BONUS_RATIO, MAX_SLEEP_AVG and STARVATION_LIMIT.
If I tune this variables I can tweak the performance
of the
scheduler, but in the new kernel I cant find any documentation that
allows to successfully modify the scheduler.
</p>
<p style="margin-bottom:0in">I would gladly appreciate any
information related to the scheduler in the new kernel, or
documentation about the new variables that are similar to the ones I
mentioned.</p>
<p style="margin-bottom:0in">Thanks in advance for your time.

<br></blockquote></div>There are present sysctl scheduler tunables in dir /proc/sys/kernel/sched_*<br><br>You can do the tuning according to your requirement. <br><br>But i think there is a better way to increase the calls to the sip server.<br>
<br>To increase the calls to sip server means to maximize the run-time of sip server process.<br><br>This can be done by increasing the nice value of that process, with the "renice" command. Only root user can specify the negative values. I think this should do the job.<br>
