This is usually windows scaling issues. Many sites are still using
broken firewalls which can't deal properly with TCP window scaling. TCP
Windows Scaling was declared an official TCP/IP standard in 1992,
proposed standard some years earlier. But as the most common desktop
OS:es have not been using TCP Window Scaling many vendors ignored the
issue... but the Linux kernel people have selected not to ignore the
problem and make it visible by not aggressively working around
brokenness.
