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 motivated by the observation that transferring files to and from sources is just deathly slow, and that while fcp does a good job helping that, it is just a patch covering a deeper issue.
