Could it be that some kind of Spectre mitigation is active? I just read about |
| 20 |
some massive performance problems in Kernel 5.19+ on Skylake CPUs. Stable |
| 21 |
gentoo kernel was upgraded to 6.1 recently, which could also be affected by |
| 22 |
this problem. |
| 23 |
See https://lkml.iu.edu/hypermail/linux/kernel/2209.1/02248.html |
| 24 |
|
| 25 |
Try turning the mitigations off or revert to a 5.15.x kernel. |
