Found this interesting thread in the OpenSUSE mailing lists about the performance losses observed by an user in Tumbleweed on a Lenovo P72 with a Core i7-8850H CPU. OpenSUSE seems to be using Indirect Branch Restricted Speculation (IBRS) compared to Retpolines in other distros including Fedora which is speculated to be causing a difference in performance.
