Could it be that some kind of Spectre mitigation is active? I just read about some massive performance problems in Kernel 5.19+ on Skylake CPUs. Stable gentoo kernel was upgraded to 6.1 recently, which could also be affected by this problem. See https://lkml.iu.edu/hypermail/linux/kernel/2209.1/02248.html Try turning the mitigations off or revert to a 5.15.x kernel. Alex
