I'm using the following patch to distinguish Directory traffic from OR
traffic on my test relay:

}
if (connection_counts_as_relayed_traffic(conn, now)) {
As a result, I get a very low fraction of Directory traffic compared to OR
traffic. I wonder why that is the case.
In the attachment you can find a histogram of 10-second intervals and the
sum of read and written bytes in KiB/s. There are only very few Directory
connections with very little bandwidth consumption in that histogram. This
is a 500 KiB/s middle node running for 24 hours.
