compression (zlib) is the Tor bottleneck on a 1.5Ghz C7. crypto
throughput with patched openssl (dynamic padlock engine) is:
SHA-1 throughput 268,405.03kB/sec with 8k blocks
SHA2-256 throughput 263,643.08kB/sec with 8k blocks
AES-128-CBC throughput 1,029,006.84kB/sec with 8k blocks -> yes, 8Gbs of AES!
AES-256-CBC throughput 779,103.35kB/sec with 8k blocks

hardware entropy throughput is 50kB/sec to 8+MB/sec depending on
XSTORE instruction and user space entropy daemon configuration.
