Yes! Forgot to mention that: we’re using PersistentTerm as well (have been since it was in PR last year), and it’s definitely provided gains as well. Huge thanks to @benwilson512 and team for that.
FWIW, when I say that our response times are manageable, I may have been understating. Our overall times have been reduced to a third of what they were.
It’s still a mystery to me exactly what’s happening, but it’s now a low priority mystery for us.
