Same.

I'm not certain that it's only USB ethernet.

On my (gigabit) ethernet, my CPU server is about 15% the speed of
my Linux work machine, averaging something like 15 MiB/second.
But with different URLs (I picked some OpenBSD mirrors), the results
vary wildly:

        cpu% hget http:$url | tput
        10.98 MB/s
        20.70 MB/s
        17.07 MB/s
        15.59 MB/s
        <snip>
        10.70 MB/s
        10.77 MB/s
        <snip>
        15.17 MB/s
        15.26 MB/s

        $ curl -o /dev/null http:$url                                                                               <
          % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current
                                         Dload  Upload   Total   Spent    Left  Speed
          0     0    0     0    0     0      0      0 --:--:-- --:--:-- --:--:--     0

Compare this one, where 9front beats Linux handily:

        cpu% hget http:$url | tput

        70.15 MB/s
        72.19 MB/s
        73.59 MB/s

        $ curl -o /dev/null http:$url 
          % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current
                                         Dload  Upload   Total   Spent    Left  Speed
