before bringing it forward to LNX netdev and with the risk of restating
something, I wanted to hearken for the take of this here, since it's
also bloating related - when looking at it from the link
clogging/flowyness point of view.
I first surmised some DQL (as done for driver rings - BQL) introduction
to the TCP hard limit could improve perceived flow latency - though the
current hard limit is perfectly enough in conjunction with the window
As of what I measured here
it rather appears introducing a kind of per socket settability of the
advertising hard limit maybe organized on a link/receive side realm (be
it a subnet or a flow group) for performance can improve the scene.
Sure, it's not possible to align both ends (RCV/SND) always, but for the
back end world and therefore as a general statement it should hold true.
Let me know if I'm totally going astray.
