[asterisk-biz] Benchmark

[Matt Teagarden]

Yea same here,  preemptable kernel,   strip out all the stuff 
(drivers,fs  etc..) that I don't want.  I generally don't run any loaded 
modules as I compile them into the kernel. I am currently running 2.6.21 
as I haven't upgraded in awhile.  I also have some patches applied for 
enabling reiserfs compression.   I use a compressed reiserfs partition 
for long term cdr storage and asterisk log storage(saves an incredible 
amount of space!).     I haven't played with timers and a few other 
things in search of the perfect asterisk kernel,   but maybe it's time I 
should!   I do make sure the kernel is compiled cpu specific.   I also 
have changed ulimit settings while loading asterisk,   I have run into 
max files open errors without upping the default limit on my current 
setup.  (ulimit -Hn 9999)  I know that people have had mixed results 
with HT turned on (with intel platforms) but so far I have not had any 
issues. 

Let me know if there is anything else about my setup you would like to 
know..
