cosine() ones cleaned up now too. I don't see perf issue with the array: guess this whole shebang relies on escape analysis anyway. |

I backported this one to 9.x. As I cleaned up commits, this one was committed in 9.x as part of #12681 |

Estimates taken from empirical run times (actions history), with a generous buffer added.

Now that we have integrated benchmarks, it is easier to take care of this code.
This is pretty straightforward change:
I see the same performance (no logic was changed)
Note: not much can be done with cosine method, for obvious reasons that it is a slow complex nightmare, IMO we shouldn't support it anyway. But we can't let that get in the way of trying to improve the other ones.
