Here's the read and write statistics from the ExtraInfo descriptors from a handful of the fastest default-policy and reduced-policy relays:
Pardon my tangent, but: The enormous discrepancy in read/write values, if accurate, makes a mockery of AccountingMax for purposes of tracking bandwidth used.
These are per-port exit stats. I believe AccountingMax is for *all* relayed traffic.
For every byte the exit writes to a port, that is a byte it had to read on an orconn from another relay.
Similarly, for every byte an exit read from a port, that is a byte it has to write to an orconn to another relay.
Thus, for exit relays, *total* upstream and downstream will be mostly symmetric. There may be some discrepencies for packing data into 512 byte cells, though.
