I was wondering if there was a guide to tweaking the linux kernel so that Asterisk runs best. I know in 2.6.13 they added adjustments to change the timer frequency from 100, 250 and 1000Hz. But then there are the different preempt options and the high resolution timers patches. Has anyone taken the time to see what effect it all has on asterisk? What timer source does Asterisk use if you don't have any hardware digium cards installed?
