this notice does indicate you are successfully using the dynamic aes-ni engine. public key operations and zlib still dominate processing. however, you are getting not only 3x-10x+ performance improvement in AES ops, but also avoiding nearly all side channel attacks against AES! it would be useful to be able to toggle this engine on and off at run time without a restart of Tor to measure actual performance comparison of a running node with and without AES-NI acceleration. best regards, _______________________________________________ tor-talk mailing list [email protected] https://lists.torproject.org/cgi-bin/mailman/listinfo/tor-talk
