... Don't tell me AES is the bottleneck on a Padlock system. VIA C7 can process way more AES blocks than the (typically crappy) NIC can handle.
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!
