I don't understand the point of this type of comment. It's a summary of something short (that didn't need a summary) and it misses critical information.
A lot of people (myself included) read the comments first, and then visit the article if our interest is piqued. That's why comments like the GP get upvotes.
It doesn't really need a "summary" though. Maybe you could add something to the conversation? Like "Oh, I didn't know libturbo was that slow" or "I'm glad Cloudflare is contributing back to the project."
