Looking at Atlas your relay advertises 2.45 MB/s which is quite low for
a 100Mbit connection: 2.45 MByte x 8 = 19.6 MbitWhat value do you have
in your torrc? For a 100mbit connection it should be at least:
BandwidthRate 12 MB

Yep, surely.
You currently push 3Mbps of traffic, which is correct for this kind
of hardware.
All "cheap" hardware (raspi, banana, olimex, pine…) suffer of the
fact they
don’t have crypto hardware acceleration and do software encryption.
And so is
very slow (10-100× factor) even compared to low end amd64 CPU with
AES-NI
extension.
According to 'openssl speed aes-128-cbc' the Allwinner A20 CPU in
Banana Pro is
capable of about 25 MBytes/sec in AES performance. While that won't
translate
1:1 into Tor performance, as Farid noted in his case the CPU isn't
being a
bottleneck, with only 10-20% CPU load observed.
@Farid,
According to top the CPU hovers around 10-20% most of the time.
I wonder is it 20% across both cores, which could be 40% of one core
(since
Tor is not multithreaded enough), and at least somewhat closer to not
being
practically idle. Can you launch 'top' and press '1' there to check?
Also seems unclear why it didn't get the guard flag for so long, does
your
public IP address change from time to time? Or do you turn the relay
off and
on for whatever reason.
