Here's the result of a benchmark sending a 1GB file over a Gb/s ethernet network:
vanilla:
real    0m9.446s
user    0m0.493s
sys     0m1.425s

sendfile:
real    0m9.143s
user    0m0.055s
sys     0m0.986s

The total time doesn't vary much (the reduction above is just jitter).
But it reduces user+sys time by almost a factor of 2.

Note that is changed Giampaolo's patch to call sendfile on the whole file, not by block.
