vdmitrie added a comment.

The performance run did not reveal any regression while there were couple of gains (13% and 18% - two tests in different benchmarks, one of them was targeted). On cpu2017 the numbers are nearly flat.
Tested with benchmarks SPEC CPU2017, Coremark Pro, SPEC HPC 2021, and a few more.
