[tor-relays] boost CPU on a Tor relay

[Sebastian Urbach]

Hi,

AES-NI is by far the most powerful feature from your list. From my point of 
view absolutely necessary. If theres no CPU Upgrade reachable for you i 
suppose you can wait for the tor alpha version to become fully multithread 
capable. This should be reality in the near future.

Hi,

A Tor relay currently going 33MB/s could go a lot faster but CPU is at
93% usage - this is the bottleneck. Here is the output of /proc/cpuinfo

power management:

it also goes down to processor 1 - processor 7

Any ideas how this could be boosted? OS is Debian wheezy. No aes-ni
hardware acceleration, no openssl benchmarking or customization
currently. advices? Thank you.
