We have Streaming SIMD Extensions
from blake2b-simd.
Do we have comparable benchmark tests for the (optimized) erasure code? It would be interesting to see if it show a similar performance characteristic.

Interesting thing to observe here is that native Go code itself gives low performance which provides better performance on my laptop itself.

Test with the official BLAKE implementation
blake2s gives better results than blake2b (twice as quick).
Seems to indicate that there's some kind of performance penalty on Atom when executing SSE with 64-bit operands

In Golang, blake2b-simd is still getting a 1.5x speed up (59MB/sec) compared to the pure go (non-assembly) version (40MB/sec).
However the test above indicates that we could potentially double this by examining where the blake2b reference implementation gets its performance from, and (re)implement this in go assembly. The question is whether this is worth the effort or not.
Conclusion seems to be that the SSE implementation of Atom helps to a little extent but is not up to par with the implementations on other chip sets.
from blake2b-simd.
Closing the issue for now.
We can always spend the time to get up to par with the plain C reference implementation when the need arises (2x improvement).
