Let's get this straight though: this is *not* a Linux bug. However,
some broken boxes and routers do not correctly handle TCP window
scaling. TCP window scaling is important to get the maximum throughput
on TCP connections.

If you run a Linux kernel 2.6.18-rc5 or above (such as 2.6.18), you
can work around this problem for specific sites (rather than hurting
TCP performances globally using the aforementionned sysctl) by doing:

# route add -net 212.157.227.0 netmask 255.255.255.0
  gw 192.168.0.254 window 65535

(all on one line, replace 192.168.0.254 with your default router address)

Also note that TCP window scaling has been defined in RFC 1323 back in
1992...
