I suspect hardware issue with your IPC, maybe not all cores of the I7
cpu are used since the IPC is fan-less. Shooting in the dark, try a
different scheduler, the kernel 6.12.x comes with three scheduler:
deadline (the default), kyber and bfq. To see the available scheduler
simply run:
# cat /sys/block/sda/queue/scheduler
change "sda" according to your SSD device, to try another scheduler run:
# echo bfq >/sys/block/[TheSSD]/queue/scheduler
If you want to know more about Linux kernel scheduler looks at
"linux-source-6.12/Documentation/block/" directory of the kernel sources.
Kind regards,
