TCP window scaling, or zomg the Internet works for me again

Posted on November 19th, 2008 by Sacha Chua

Sites such as aircanada.com, pcfinancial.ca, and (horror of horrors!) torontopubliclibrary.ca had gotten _unbearably_ slow on Linux.

Here's how I fixed it (as root):

echo 0 > /proc/sys/net/ipv4/tcp_window_scaling

I love you, Ubuntu forums.
