Which WordPress permalink structure is better in terms of performance and SEO:
Does it matter?
Google has big discussion here. But it's not from a WordPress perspective.
Which one should I use and why?
Edit: I noticed I get an advantage using
/%post_id%/%postname% since any mistake etc after
sitename.com/123/wrong-words?some=params&etc=etc gets redirected to the correct post. But for
sitename.com/123/correct-full-postname/someword generates a 404.
