Do you have any figures on (large) MTU size vs performance on a current
commidity system?

What qualifies as large?  I ran some measurements out to 9k w/GigE a few
years ago.  (Something like 100 byte increments.)  I can try to find the
data if anyone is interested.  I may try to run a similar experiment on 10
GigE with modern hardware, and I think these cards can go out to 16k as
well.

Anything above 1500 bytes (up to 64k would be interesting).

There are some arguments that going to much larger MTUs could be of
substantial benefit other than CPU cycles, but this is harder to quantify.
See <http://www.psc.edu/~mathis/MTU/>.

Thanks for the info.
