Linux Cuts Early Boot Memory Allocator Time Dramatically

Original: Linux's Early Boot-Time Physical Memory Allocator Big Speed-Up: ~268s to ~50ms

The Linux kernel's early boot-time physical memory allocator, memblock, has seen a major speed-up, with initialization times dropping from roughly 268 seconds to about 50 milliseconds. The optimization is expected in kernel 7.4 and dramatically reduces boot overhead on large-memory systems. Developers and kernel enthusiasts are discussing the technical changes behind the improvement and what it means for faster system startup.

Why now: A dramatic performance improvement in a core part of the Linux kernel is notable to developers and system administrators.
