Corinna Vinschen 609d2b22af Fix limited Internet speeds caused by inappropriate socket buffering 
Don't set SO_RCVBUF/SO_SNDBUF to fixed values, thus disabling autotuning.

Patch modeled after a patch suggestion from Daniel Havey <dhavey@gmail.com>
in https://cygwin.com/ml/cygwin-patches/2017-q1/msg00010.html:

At Windows we love what you are doing with Cygwin.  However, we have
been getting reports from our hardware vendors that iperf is slow on
Windows.  Iperf is of course compiled against the cygwin1.dll and we
believe we have traced the problem down to the function fdsock in
net.cc.  SO_RCVBUF and SO_SNDBUF are being manually set.  The comments
indicate that the idea was to increase the buffer size, but, this code
must have been written long ago because Windows has used autotuning
for a very long time now.  Please do not manually set SO_RCVBUF or
SO_SNDBUF as this will limit your internet speed.

I am providing a patch, an STC and my cygcheck -svr output.  Hope we
can fix this.  Please let me know if I can help further.

Simple Test Case:
I have a script that pings 4 times and then iperfs for 10 seconds to
debit.k-net.fr

With patch
$ bash buffer_test.sh 178.250.209.22
usage: bash buffer_test.sh <iperf server name>

The output shows that the RTT from my machine to the iperf server is
similar in both cases (about 170ms) however with the patch the
throughput averages 129 Mbps while without the patch the throughput
only averages 11.7 Mbps.  If we calculate the maximum throughput using
Bandwidth = Queue/RTT we get (212992 * 8)/0.170 = 10.0231 Mbps.  This
is just about what iperf is showing us without the patch since the
buffer size is set to 212992 I believe that the buffer size is
limiting the throughput.  With the patch we have no buffer limitation
(autotuning) and can develop the full potential bandwidth on the link.

If you want to duplicate the STC you will have to find an iperf server
(I found an extreme case) that has a large enough RTT distance from
you and try a few times.  I get varying results depending on Internet
traffic but without the patch never exceed the limit caused by the
buffering.
