@IvaVladimir I'm not sure at which numbers to look there. Because it looks like there you just report numbers of the current master (with this patch here already integrated) vs your new changes from https://github.com/openjdk/jdk/pull/26747.

What I would have liked to see: performance before and after this patch here.

Is https://github.com/openjdk/jdk/pull/26747 a simple RFE, or is it a fix for a regression?
