Linux kernel CPU performance issues?
Linux kernel CPU performance issues?
Hello, I own an old Core 2 Duo (T7400) that may freeze during boot with the latest Linux kernel 4.18. My Intel Atom N450 also doesn’t fully start up but runs slowly—especially when using the CLI. On boot, it reports issues like an unstable clock. Testing pings to localhost shows much better performance in the newer kernel (1-2 ms) compared to 4.14 (0.05 ms). The Core 2 struggles significantly, while the Atom N450 behaves more predictably. Is this a known issue with these processors on newer kernels? Anyone else experiencing similar problems?
I have an AMD FX 8320 here. It seems quite outdated, but it’s definitely an older processor. There’s no noticeable slow start because I run my OS on a Samsung SSD. The system I’m using is Arch Linux with KDE Plasma, and I don’t rely on the LTS kernel, which means it’s pushing the boundaries of technology.
It seems you're checking if everything is identical across the system and just choosing between two kernels at startup. It would be odd if the kernel itself had a problem. It's possible, though. You might want to switch to a different distribution using the same kernel version. If the issue persists, it could point to a fault in the kernel rather than configuration problems with newer versions.
