Hey Farid, Have you found an interesting low cost hardware since this last message ? Sometimes I try to look for it, but there's a lot of little cards like RPi, Banana... sadly I think it has not enough CPU power to play with a lot of Tor traffic :s
On the torserver webpage, there's a command line to know if the cpu has AES-NI acceleration.
cat /proc/cpuinfo | grep aes
For fun, I've tried on a laptop with Intel Core 2 Duo... no result shown after this command. So sadly this laptop will not be enough strong to have fun with this kind of crypto... it's sad because it's not burning a lot of watts!
Farid Joubbi :
OK. I thought from the beginning that my relay running the Banana Pi would be capable of handling more traffic. I have asked about it before, and got some really good answers. I still can't completely explain why it does not handle more.
