Compound TCP is a Hybrid TCP Congestion Control approach. You can also enable ECN (lossless congestion control feedback):
If enough end users enable ECN, core providers may be inclined to deploy AQM with Packet Marking too… And as Home Gateways are those which are prone to ECN implementation bugs, a full disconnect from the internet (rather than certain sites not reachable) is quite easy to quickly diagnose.
Also, enabling ECN gives you more retries with the SYN (3x ECN+SYN, 3x normal SYN), so in a heavy congested / bufferbloated environment, your small flows might get through eventually, with higher probability.
netsh int tcp set global congestionprovider=ctcp netsh int tcp set global ecncapability=enabled
The use of
netsh int tcp set global congestionprovider=ctcp has been
depreciated. In order to set or change the congestionprovider the
following command must be used:
set-nettcpsetting -CongestionProvider CTCP
However, CTCP is the default on windows 8 and later.
get-nettcpsetting to view other settings that used to be part of
netsh tcp global.
ECN is a global setting and is still configurable, even on clients, through netsh by running:
netsh int tcp set global ecn=enable
On Windows Server 2012, you can change this setting through the custom template or netsh.
