Re: [tor-relays] Why can't I see more traffic? (is my banana too weak?)

Could it be that it is due to the quite slow hardware, even though I know that it is able to push more traffic?

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.

Generally speaking, the bottleneck of a Tor relay is CPU, not bandwidth. Even high end Intel CPU is not able to deliver more than 300Mbps (one core of 2Ghz Xeon is ~ 100Mbits, standard CPU is ~ 300Mbps, best known Tor relay currently handle 500Mbps).
