[asterisk-users] Do extra CPU's help?

[Colin Anderson]

In 2.6.15 kernels and higher, you can use "taskset" to pin a task to a
certain CPU. Here's a way to set httpd to the 2nd processor in a 4 way
system:
 
HTTPDPID=`ps -A | grep -a -A0 "httpd"`
taskset 0x00000002 -p  ${HTTPDPID:0:5}

Do extra CPU's without hyperthreading help?

hyperthreading results seem to vary from different people you talk too.

Hi all,

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.
