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. -- Julien --FkvFx3Q7o6N1sDBE46uxD8pxFoMSO0bwE Content-Type: application/pgp-signature; name="signature.asc" Content-Description: OpenPGP digital signature Content-Disposition: attachment; filename="signature.asc" -----BEGIN PGP SIGNATURE----- Comment: GPGTools - https://gpgtools.org iQEcBAEBCgAGBQJWZaeUAAoJEKVlQ5Je6dhxXasH/iQefxycNBShEpD0h61mbotm zQDU4TN1pB3XE/6IWSgiAnSEm+ssyA4vfzrTI3+ceMhTcsT685IPIpBKLF5fARqI G9IZ7jCuglqNk/yQrAJWRPMGiF8bHvq4Vk7sh7AymUFD05U9gQNlP/YAoS/jPhQS 1RblQZEl4lWX300mgeXRY90l6KgOao1zGZ5e4sPZ2QXP4w8T8FpWq0kEg7NkTP5M 4SAsWj22U/YLiaFfmRM1VapiVz6Gz/ltdnczopwrhfWitnkp27/iqafIuq4lYDwL emQTxrxtSJJ4ZYPu3IFuiQwBK3D3FRANIddvhDPfIIOsx/596p90ttrrdaK/0XI= =STNt -----END PGP SIGNATURE----- --FkvFx3Q7o6N1sDBE46uxD8pxFoMSO0bwE--
