This is an awesome reply that I would like to see here. Do you mind sharing more details on what type of cache or use case needs the performance you mentioned? Database bufferpool?

> a lot of these practical details have never been written down a far as I can tell, it is passed along as lore and beer convos

I wish the valuable knowledge could be written down and shared.

Yup, I am on the same page as you, after seeing the many state-of-the-art having similar miss ratios, I am inclined to think we are close to the maximum possible hit ratio bounded by the limited information from the request history (information theory).

I’d be happy to chat more, this is probably best taken offline. My contact details are in my profile. I have had an ambition to write up everything I know about this subject, both theory and practice, but I never get around to it as a practical matter.
