Yes, there are a lot of differences.

https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/tree/arch/x86/configs/x86_64_defconfig
https://git.archlinux.org/svntogit/packages.git/tree/trunk/config.x86_64?h=packages/linux

But who knows what exactly is affecting it?

Arch uses CONFIG_HZ_300=y and x86_64_defconfig uses CONFIG_HZ_1000=y,
I doubt that has anything to do with it?

Thanks,
Diego
