Well, that one is easy: port 80. :)

Okay, in the last line we can't say this.  But in all other lines the
"other" entry has fewer streams than port 80 which is among the top 10.
Only the last line does not include port 80, and the "other" entry has
more streams than top-1 port 8080.  Could be that this relay does not
permit exiting to port 80.  Or that port 80 was 11th or 12th in terms of
bytes.

Hope this is useful anyway.

All the best,
Karsten
