Comment 29 for bug 59331

Hey,
This is also a problem for me. Ubuntu 14.04.2 LTS Kernel 3.13.0-32-generic

net.ipv4.tcp_window_scaling = 0
"fixes" the problem for me

also using these settings works but slows everything down:
net.ipv4.tcp_wmem = 4096 16384 512000
net.ipv4.tcp_rmem = 4096 87380 512000
net.ipv4.tcp_window_scaling = 1

A better and more out-of-the-box solution would be appreciated.
