I wrote a previous post on why MVCC is interesting, and how it relates to the topic at hand. It's the first link in the article.

I don't think that it's accurate to say to say that there are only two ways of doing this. There are more than two, and there's another post by my colleague Amit Kapila which talks about that. That's the second link in the article.

We have in fact done benchmarks. We plan to publish them.

But you can't put everything into one article. Several people mentioned thinking this one was quite long, and it barely scratches the surface of the topic. If I'd included an in-depth discussion of all the topics you raise here, it would have been four or five times longer. To try to avoid that, yet give the context you want, I linked to previous posts which cover this topic, some of which were written explicitly to provide context for this article.

But I'm sorry you didn't like the article. I tried my best.
