Oh, that's a good point. I don't know if that means that the crypto code won't use 64-bit optimizations though. The Crypto++ benchmarks posted by its author, Wei Dai, are: http://cryptopp.com/benchmarks.html All measurements are CPU cycles per byte hashed. Intel Core 2 1.83 GHz, 32-bit mode: SHA-256: 22 Tiger: 8 Pentium 4 (Northwood) SHA-256: 41 Tiger: 16 Opteron 2.4 GHz: SHA-256: 21 Tiger: 7 Okay, and I've just run the Crypto++ self-benchmark script on one of our servers (deharo2 -- Pentium 4 3.0 GHz): SHA-256: 45 Tiger: 15 And on my workstation (Athlon64 2.4 GHz): SHA-256: 22 Tiger: 7 Regards, Zooko _______________________________________________ tahoe-dev mailing list [email protected] http://allmydata.org/cgi-bin/mailman/listinfo/tahoe-dev
