 Hi,

 I got a bit of interest of having the performance improvements for
short-lived TCP connections in 10-stable.  Just to share the current
status to a wider audience:

 - I maintain a stack of our TCP performance related patches for
10.2-RELENG here:

https://github.com/verisign/freebsd/commits/10.2/tcp-scale

 - All these performance patches are in 11-CURRENT since (at least)
August 2015.

 - If these patches are indeed quite stable, I would prefer to have
other traffic/real life examples where these changes also improve
performances (in top of our specific DNS over TCP traffic) before
starting to MFC in 10-stable.

 - Currently all (few) concerned users I am aware of are happily using
11-CURRENT.

 Of course, all these improvements will be available by default in
11.0.0 anyway.
