And the list of applications which do
sock = socket(...);
map = mmap(...);
write(sock, map, bytes);
are? There are not very many that I know of and if you look carefully
at the bandwidth graphs in LMbench you'll see why. There is a cross
over point where mmap becomes cheaper but it used to be around 16-64K.
I don't know what it is now, I doubt it's moved much. I can check if
you really want.
