I was recently fiddling with TCP performance on long-fat links,
and noticed that iproute2 seems to allow one to set a per-route window.
is this implemented in the stack? I gave it one try and it didn't
seem to work, but I admit I haven't delved into the code yet.
we'd like to tune for some 10Gb, 3-6 ms links, mainly to move large files
between our sites. this is not CERN-scale stuff, but being able to configure
large windows on particular routes sounds terribly convenient...
thanks, mark hahn

You can set the window, but you must lock the setting.
