There are certainly many others way to get gathering, without adding an
artificial delay. There are already delay slots built into the code which could be used to trigger the gathering, so with a little bit different architecture, the
performance increases could be achieved.

Some implementations actually do write gathering with NFSv3, even.  Is
this interesting enough to play with? I suspect that just doing the work for
NFSv2 is not...

Write gathering does still apply to stable NFSv3/v4 writes, so an
optimisation may yet benefit applications that use O_DIRECT writes, or
that require the use of the "noac" or "sync" mount options.

I'm not aware of any ongoing projects to work on this, though, so it
would probably be up to those parties that see it as beneficial to step
up to the plate.


Cool. If anyone is interested, I would be interested in participating in a design
discussion and perhaps even prototyping.

   Thanx...
