Linux boot-time memory allocator gets massive speed-up

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

A major optimization to Linux's early boot-time physical memory allocator (memblock) cuts initialization time from roughly 268 seconds to about 50 milliseconds. The change, headed for Linux 7.4, was reported by Phoronix and is drawing attention among kernel developers and system administrators, since dramatically faster memory initialization could shorten boot times on large-memory machines.

Why now: A dramatic performance improvement in the Linux kernel's boot process is notable to developers and sysadmins.
