Edit: note that IPv6 does not slow down IPv4. Ipv6 is a different from IPv4 in 5 major areas as follows:
- addressing and routing,
- network address translation,
- administrative workload, and support for mobile devices.
- IPv6 also includes an important feature: a set of possible migration and transition plans from IPv4.
Reason for editing: see comments.

By running this code you can disable IPv6. If you do no have that directory, you can edit your grub menu:
sudo su -
echo 1 > /proc/sys/net/ipv6/conf/all/disable_ipv6
gksu gedit /boot/grub/menu.lstthis file have bunch of boot comments. Now navigate ubuntu 9.04 generic 2.09 or somthing like this.
