Is 9p suitable for this? How will the 40ms latency affect 9p
operation? (I have 100Mbit).
With a strict request/response protocol you will get no more
than 64KB once every 80ms so your throughput at best
did you do testing at regular lan latencies? what i see on my networks
is usually = 30µs.

I induced latencies similar to those found on the Internet. My tests at LAN
speeds (500us in my sub-optimal setup) had 9P at essentially the same
transfer rate as HTTP. My work was
issuing multiple outstanding

the question for me is how does one make this easy and natural. one way
is to allow the mnt driver to issue multiple concurrent reads or writes for
the same i/o. another would be to
