This is an extremely aggressive, high-performance optimization path. By choosing Void Linux (musl) with a custom kernel and a native Wayland compositor, you are shedding decades of legacy code.
Important Reality Check: Applying mitigations=off, forcing a 1000Hz kernel tick rate, and permanently setting a performance CPU scaling governor will yield incredible, instantaneous responsiveness. However, this will severely impact your battery life and disables critical Spectre/Meltdown vulnerability protections. This stack is designed strictly for a tethered, trusted-code performance environment.
