FWIW, Poly1305 uses _a lot_ of multiplications. I expect it to perform poorly with SPARC V7 code. In fact, UMAC from the previous default of aes128-ctr + umac-64-...@openssh.com already uses quite a lot of multiplications, although fewer than Poly1305, and I suspect it underperforms with SPARC V7. People who find scp throughput very slow on sparc may want to experiment with switching to aes128-ctr plus one of the hmac-*-e...@openssh.com MACs. -- Christian "naddy" Weisgerber na...@mips.inka.de
