Any observed Performance Improvements after upgrading to 19.5.x

Under the hood apparently many code optimizations have been happening as advertised and I am wondering if there are any 'benchmarks' present to verify?

I am running some daily script where batch records are created on the server and I get precisely the same record creation durations etc of all versions since FM18 ...

What subjectively feels faster is interacting within portals but I have no metrics for that.
Did anyone see anything significantly improved?
