between Asterisk (kernel and standard native application) and differents
hardwares components (disk, processor, memory)</span></font></p>

<p class=MsoPlainText><font size=2 face="Courier New"><span lang=EN-GB

<p class=MsoPlainText><font size=2 face="Courier New"><span lang=EN-GB
style='font-size:10.0pt'>I have a look on the code of some asterisk application
(Dial, MeetMe, …) and It seems to me that the main work of any

<p class=MsoPlainText><font size=2 face="Courier New"><span lang=EN-GB

explain disk usage ? Swap temporary event,.. ?</span></font></p>

<p class=MsoPlainText><font size=2 face="Courier New"><span lang=EN-GB
style='font-size:10.0pt'>In conclusion, I think that processor is the main
point in asterisk architecture. Memory and disk are less important in asterisk
performance. Can you agree with this conclusion ?</span></font></p>
