[asterisk-users] Do extra CPU's help?</DIV>
<DIV><BR></DIV>Hi all,<BR><BR>We have Xeon-based system with only 1
(hyperthreaded) CPU (in a HP DL360). We are seeing high load on multiple
meetme session as well as g729 transcoding. My question is will putting
an extra CPU help or does Asterisk just run on a single CPU.
