Interestingly, screaming appears to be faster than hyperscreaming in this case @Veedrac

Veedrac commented 8 years ago

It's possible hyperscreaming is saturating something. I don't really know, though.

@vks Was this with RUSTFLAGS="-C target-cpu=native"?

@Veedrac No, here are the results with native optimizations:

Looks like hyperscreaming is getting even slower.
