<div> Yep, surely.</div>
<div> </div>
<div> You currently push 3Mbps of traffic, which is correct for this kind of hardware.</div>
<div> All "cheap" hardware (raspi, banana, olimex, pine…) suffer of the fact they</div>
<div> don’t have crypto hardware acceleration and do software encryption. And so is</div>
<div> very slow (10-100× factor) even compared to low end amd64 CPU with AES-NI</div>

<div>According to 'openssl speed aes-128-cbc' the Allwinner A20 CPU in Banana Pro is</div>
<div>capable of about 25 MBytes/sec in AES performance. While that won't translate</div>
<div>1:1 into Tor performance, as Farid noted in his case the CPU isn't being a</div>
<div>bottleneck, with only 10-20% CPU load observed.</div>

<div> </div>
<div>I wonder is it 20% across both cores, which could be 40% of one core (since</div>
<div>Tor is not multithreaded enough), and at least somewhat closer to not being</div>
<div>practically idle. Can you launch 'top' and press '1' there to check?</div>
<div> </div>
<div>Also seems unclear why it didn't get the guard flag for so long, does your</div>
<div>public IP address change from time to time? Or do you turn the relay off and</div>
<div>on for whatever reason.</div>
