Does anyone know how to use the HardwareAccel feature correctly ? Somehow im not able to get this working on my Intel cpus wit the hardware AES engine built in. It would be great to get it up and running because 24 cores could do some nice work for tor ;-)

The cores don't help much. Depending on your bandwidth you have to run one Tor process per core.

AES Crypto Acceleration instructions: https://www.torservers.net/wiki/setup/server#aes-ni_crypto_acceleration

At high bandwidth, enabling RPS helps too (symptom: core 0 is maxed): https://www.torservers.net/wiki/setup/server#receive_packet_steering_rps

I missed you at 28c3, let us meet up again some day!
