Linux slashes early boot memory allocator time from 268s to 50ms

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

The Linux kernel is set to receive a major speed-up to memblock, its early boot-time physical memory allocator, cutting initialization times from roughly 268 seconds to about 50 milliseconds on large systems. The optimization, covered by Phoronix ahead of the Linux 7.4 cycle, dramatically reduces boot times for machines with huge amounts of memory. Developers and kernel watchers are praising the scale of the improvement.

Why now: A near-instant reduction in a core kernel initialization path is a striking engineering result that draws broad technical interest.
