This is not what I am talking about, JIT caches with PGO data work in a different way.

I don't think I'm familiar with this (I may have come across it but didn't identify it by name when I worked with Graal?), could you provide a link? :o Thanks!

I have provided links above, there are also a couple of Java Language Summit, Code/Java ONE and Google IO talks about them, but I would need to search for them. Can provide them later.

Thanks, I know of this stuff but I don't think I would've been qualified to form an explanation/overview of them. It would be nice to have these in a post though!
