Slow Internet on Fedora 8.
LAN connectivity was fine.
Speed Browsing from Windos XP was fine.
Fedora 8 x86_64 with firefox, slow in opening web pages (download speed 6k ~12k)
yum install (any updates ) would fail and start slow with alternative sites and then pickup download speed.
disable ipv6 on firefox (open firefox and on the URL bar type "about:config" search for ipv6, change the value disbale IPV6 to "TRUE")
edit /etc/sysctl.conf and add the following lines
#Control TCP Windows Scalling
net.ipv4.tcp_window_scaling = 0
