Hi,

I'm building a test asterisk server and building the latest kernel I got 
to wonder if there are any specific recommendations about schedulers and 
so forth for optimum performance.

There are a few areas that raise questions in my mind and I wonder if 
anyone has any opinions/comments on which settings are most suitable for 
use with asterisk:

SLAB Allocator (SLAB or SLUB?)
Tickless System (?)
Preemption model (?)
IO Scheduler (Anticipatory, Deadline or CFQ?)
Flat or Sparse Memory (?)
Timer Frequency (100Hz .. 1000hz)

Cheers

Alan
