We submitted Keccak to the ECRYPT Benchmarking of All Submitted Hashes (eBASH) project and the first results are appearing.
eBASH measures the speed of hash functions on a wide variety of machines using a tool called SUPERCOP. The software reports the number of cycles necessary to hash messages of different sizes, from 8 to 4096 bytes, and extrapolates for longer messages. It benchmarks many SHA-3 candidates, as well as older hash functions as a comparison.
The first results confirm speeds that are close to 10 cycles/byte on the reference platform defined by NIST. More precisely, 10.14 cycles/byte are reported on the machine named "cobra" (Intel Core 2 Duo E4600) using the amd64 architecture and 31.52 cycles/byte when using only 32-bit x86 instructions (long messages, median).
