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 [ montmult accel via openssl 0.9.9 bn_mont_mult via-mont.pl asm optimization ] rsa 1024 394.1 sign/sec, 8710.6 verify/sec rsa 2048 84.0 sign/sec, 2973.4 verify/sec rsa 4096 14.2 sign/sec, 866.8 verify/sec dsa 1024 1024.0 sign/sec, 852.5 verify/sec dsa 2048 349.2 sign/sec, 294.6 verify/sec hardware entropy throughput is 50kB/sec to 8+MB/sec depending on XSTORE instruction and user space entropy daemon configuration. best regards,
