And I've seen the issue in hundreds of captures using a profiler. I suppose we just have a different definitions of the what "worse performance" is.

Or perhaps the fish was drown in the stats, or again different metrics.

You're not including data in your discussion of this topic. Your post included zero data.

My post on WTF locks has tons of data.

So, I'm not assuming; I'm observing.

Nobody cares what you saw in the profiler.

What matters is the performance users experience.

By any metric of observable performance, yielding is the optimal way of spinning.
