To improve network efficiency disable IPv6 if you really do not need it:

  • add NETWORKING_IPV6=no in /etc/sysconfig/network file. 
    echo NETWORKING_IPV6=no >> /etc/sysconfig/network
  • disable the ipv6 option in the kernel

make *.conf file (e.g. ipv6.conf) ) under /etc/modprobe.d/ directory and add “options ipv6 disable=1” 

echo options ipv6 disable=1 > /etc/modprobe.d/ipv6.conf

IMPORTANT: Reboot machine to introduce changes into life.
