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}

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. _____ _______________________________________________ --Bandwidth and Colocation provided by Easynews.com <http://Easynews.com> -- asterisk-users mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users <http://lists.digium.com/mailman/listinfo/asterisk-users> _____ No virus found in this incoming message.
