When setting up two N800s for ad hoc mode, I get about a 3Mbps transfer using benchmarking tools (iperf and nuttcp). Wouldn't you expect a higher transfer speed? Any ideas?

dont forget the limitations of the read/write speed of the filesystem itself

Thanks for the quick response. That's was one of my thoughts, but do you know of any good programs/methods to test file system speed

That dumps 100 MiB of data to disk, and takes 12 seconds here. So about 10 MB/s, shouldn't be the bottleneck.

But since ad-hoc is limited to 11Mb/s max, and may be dropping to lower bitrates if you have a poor link, 3 Mb/s raw throughput sounds pretty decent -- do you get significantly better throughput on other devices?
