Well, assuming it's got all the CPU/etc it needs, and is actually
on a *good* 100Mbps link... the highest throughput Tor server right
now is desync:
which is pushing about 2870 kB/s sustained on average (read+write / 2).
This adds up to a lot of bytes per month. :) And it looks like it's rate
limited by the default 3MB/6MB rate limiting, so it could be even higher
if the operator chose to raise its bandwidthrate.
If you don't give it enough cpu, or your network isn't actually 100mbit,
or it's 100mbit to the ISP but it's less to the rest of the Internet,
then it will be less. I know of several 100mbit connections that are
using 1500 kB/s, which is quite a bit different, and FoeBud ran one for
a while that could barely get past 1MB/s (they're at a different ISP and
I'm not sure what features are most influential in causing some to be
really fast and others only sort of fast.
By comparison, the fastest middleman server right now is Tonga, which
is pushing 1848 kB/s sustained.
