Network Configuration

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
