it's quite likely slower than need be
because of the wretched TCP_NODELAY
(or whatever it is on your system) not being
set by default.
set it on so as not to delay and it's typically much faster.
term% diff /sys/src/cmd/unix/u9fs/u9fs.c .

i also ifdef'd SO_KEEPALIVE because some systems haven't got it.
i changed the old (2nd edition) version of u9fs to
emulate file server permissions and permission checking
more precisely, which is to say that it must have been
missing something, but i haven't had the need for that
this time. you might find you need to adjust it though.
i haven't got that source or i'd hand it on.

No, it is substantially slower in my experience.
It serves a different purpose, namely accessing
Unix boxes. That said, I have used it as a
replacement in a pinch.
