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

November 19, 2008 - Categories: geek, linux

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.
