--------------------------------------+--------------------------------
 I'm running a Tor relay since some years on my Raspberry 3 (earlier on the
 raspi 2), but recently my internet connection started to have packet loss.
 After checking with my ISP, who didn't find anything wrong, I discovered
 that it's probably because of too many open connections.
 Running 'arm' on my relay, I see that I have:
 Connections (2561 inbound, 2115 outbound, 5 circuit)
 or:
 netstat -an | wc -l
 4897
 Besides that my raspi is a tad slow, my internet connection is quite slow
 because of the 20% packet loss.
 I've started now to work with the MaxAdvertisedBandwidth option (now set
 to 550 KB, but would like to offer 10 Mbit/s) and reduced that by nearly
 50%, but so far without any positive result (might take a while to
 propagate?).
 Anyway, my ISP UPC.ch only allows their own Connect Box (CB) to be
 connected. I'm running it in modem mode, so my router is actually doing
 the whole NAT, but that one has enough performance (tested it by directly
 connecting a client to the CB and still had packet loss.
 I'm sure this is bad for the whole TOR network :(
 I assume it might be because of the new blockades in the Arabic areas, as
 I have the problem since around 3 weeks in varying amounts.
