asterisk users - Jul 2005 - 2.6.13 Kernels

First, thanks to Kevin for the quick response to the 'minor' problem
that zaptel had with 2.6.13 kernels.

Interestingly in the kernel config you can now change the timer
frequency. According to the help messages

100 HZ is a typical choice for servers, SMP and NUMA systems
with lots of processors that may show reduced performance if
too many timer interrupts are occurring.

250 HZ is a good compromise choice allowing server performance
while also showing good interactive responsiveness even
on SMP and NUMA systems.

1000 HZ is the preferred choice for desktop systems and other
systems requiring fast interactive responses to events.


It will be interesting to see how this works with *.


Anyone else trying 2.6.13?

You are welcome :-)

It's always bugged me that my servers have to run with 1000Hz timer 
frequency just because someone decided that was better for interactive 
performance, so I consider this a big improvement.

And this appears to be the default, as well. This means that USE_RTC in 
ztdummy is going to be mandatory for 2.6.13+.
