If more than one network interface card is used, make sure the network interrupts are not all going to the same core. Run the following script to disable interrupts:
allpsr=`/usr/sbin/psrinfo | grep -v off-line | awk '{ print $1 }'` set $allpsr numpsr=$# while [ $numpsr -gt 0 ]; do shift numpsr=`expr $numpsr - 1` tmp=1 while [ $tmp -ne 4 ]; do /usr/sbin/psradm -i $1 shift numpsr=`expr $numpsr - 1` tmp=`expr $tmp + 1` done done |
Put all network interfaces into a single group. For example:
$ifconfig ipge0 group webserver $ifconfig ipge1 group webserver |
