sorry, I wasn't aware of this. Nevertheless the time spent in aes crypto
appeares to be overestimated. "openssl speed aes" gives > 200.000k bytes
per second on my active exit node with aes-128 cbc. Since this is more
than 1 Gbit/s aes crypto in theory and on the other hand 1 Mbit/s
traffic costs about 1% one core cpu cycles in real world I supposed only
about 10% cpu cycles spent in openssl aes crypto.
