Do you have benchmarks, supporting "~break-even vs. 128 bit AVX on Ivy Bridge from 128 bytes up to 2KB" as I have not found it to be the case at least on Haskell (my benchmarking code is @ https://bitbucket.org/olegoandreev/scratch/src/dd7ab9008c59c8254dd5bdb4becae20457214c3f/memcpy-test/?at=default https://bitbucket.org/olegoandreev/scratch/src/dd7ab9008c59c...).
