[Asterisk-Users] Are zttest results relevant on a system with no telephony hardware?

[Mike Fedyk]

2.6.13 has the high precision timers changes.  And people have reported 
99.99 averages with that change.

I do not recommend compiling your own kernel unless you know what you 
are doing though.  If you just want to give it a try, then use Ubuntu 
6.06, Debian Etch, FC4 or FC5 (or some other distro that packages 2.6.13 
or higher).  If you want to use it in long term production, then just 
get a TDM410B card and use hardware timers.
